Bastl - OMSynth Superlab Bundle

OMSynth Superlab Bundle - includes MINILAB, OSC, SEQ, SAMPLER PARTSKITS, KEYPAD

 

The OMSynth miniLab (v3.1) is a circuit development and performance interface designed to help inventors quickly build and experiment with creative circuits. It was designed with beginners in mind but is best suited for those with some circuit building experience. The OMSynth offers all you need to start inventing circuits to make sound and light. Potentiometers, audio mixer, speaker headphone output, battery or adapter power and more. Check out the video!

 

OMSynth comes with tutorial videos for making analog oscillators, sequencers and lo-fi digital sampler.

 

What the OMSynth IS and what it IS NOT

OMSynth IS a super useful circuit development tool that I have used as a teacher and circuit developer to make my job easier and more fun. All circuit development I have done at Bastl from sketches to finished instruments (including the BitRanger and SoftPop) has been on the OMSynth.

OMSynth IS NOT a beginners electronics course. I have provided tutorial videos and parts kits (see below) for workshops that will help beginners get into experimental circuit design quickly and helps ease them into more complex, often un-intuitive principles of electronics. That said, it will be absolutely necessary for beginner users to do extra research on their own. Rather than trying to give ALL the answers, the OMSynth is my way of giving people a powerful tool and a big boost of encouragement as they embark on the long strange journey of audio circuit design. I welcome emails from those eager to move forward or simply want to share discoveries and excitement.

 

Feel free to email Pete of Casper Electronics. More infos about breadboards & debugging, the project itself and knowledge base here.

Bastl - Kastle

Kastle (v1.5) is a Mini Modular Synthesizer with a headphone output, 2 in/out ports for interfacing other gear and it runs on batteries. It is DIY friendly and ideal for beginners in modular synthesis, but it will add some quite unique functionality to any modular synthesizer system. It delivers the fun of modular synthesis at a low cost and fits into your pocket so you can play it everywhere! It has a unique digital lo-fi sound and it can be melodic as well as very noisy and drony, soft or harsh. It is designed to be fun on its own but it is most powerful when combined with other modular gear. Kastle is an open source DIY project which runs on two Attiny 85 chips that can be reprogrammed with an Arduino. One chip is dedicated to sound generation while the other one handles modulation. Several firmwares for the Attiny chips are available thru gitHub. Videos here and here.

 

The v1.5 version combines a complex oscillator and LFO with stepped waveform generator

The oscillator section has 3 sound parameters: PITCH, TIMBRE and WAVESHAPE – all under voltage control and with 6 different synthesis modes. It has a main output and a secondary waveform output. Both can be used independently or in combination. The 3 synthesis modes available thru the main output are: phase modulation, noise mode and track & hold modulation. There are 3 more modes on the secondary OSC output: phase distortion, tonal noise mode and formant synthesis. Each mode utilizes one or two oscillators. The PITCH parameter controls the main oscillator, the TIMBRE sets the PITCH of the modulating oscillator and the WAVESHAPE depends on the synthesis mode.

The voltage controllable LFO has a triangle and square output and a reset input. The stepped waveform generator is inspired by the Rungler circuit by Rob Hordijk. It can produce 8 different voltages either in random order or in 8 or 16 step looping patterns depending on how the BIT IN is patched.

Bastl - Noise Square

Noise square is versatile generator of noises and square wave signals. There are two analog noise generators: WHITE noise and PINK noise. All other sound sources are generated digitally. There is a METALIC noise which is 6 oscillator sound bank similar to 808 but generated digitally (with analog summing) and with TUNE icluding CV control option. The DIGITAL noise output has adjustable TUNE and CV control. SQUARE and COW outputs have one square wave signal in common and the COW output has another square signal added in specific ratio to it to get the cowbell sound easily. There are 2 CV inputs for controlling the digital sound sources. For the first CV input there is a switch to select whether it controls the METALIC noise or DIGITAL noise tuning. The second CV input is dedicated to both the SQUARE and COW outputs. The CV inputs reacts in range 0-10V. Check the YouTube video.

Bastl - Dynamo

Dynamo - Dynamics and more! Dynamo is combination of 3 utility modules: envelope follower, comparator and voltage controlled switch. It combines Envelope Follower and comparator to extract gate from the envelope. On top of that there is full-wave rectifier output |EF IN| and Compressor CV curve generator.

When the Compressor CV is plugged into CV input of a VCA with offset and attenuator knobs you get an Compressor! Threshold knob on Dynamo sets the compressor threshold, Offset on the VCA sets the gain and the attenuator on the CV input sets the ratio of compression (which can also go negative). This allows you to create compressor type of effect from anything: VCA, tube module, VCF or anything that comes to your rack! Here is a YouTube video.

The other trick of the Dynamo is the voltage controlled switch section in combination with the full-wave rectifier and comparator. All pre-normalised and for what reason? Make “fake thru-zero modulation” with anything you like! Define what happens when the negative modulation is happening and adjust the zero crossing point with CV. The whole world of very deep modulations is waiting for you now…

Cinnamon is a very unique sounding, voltage controlled state variable filter filter. The presence of drive and character switches makes it a multi-flavoured spice for your sound ! This is a full kit with alu-panel.

Features

• Two passively connected Envelope Follower inputs (multiple)

• Inverted and non-inverted Envelope Follower Output

• Full-wave Rectifier Output |EF IN|

• Compressor CV Output with indication LED (only negative voltage when envelope is greater than the threshold)

Bastl - ABC

ABC - Simple 6 Channel Signal Mixer

It has 6 inputs – A,B,C,D,E and F – and two outputs – A+B+C – which is mixed in to the D+E+F output if nothing is inserted in the A+B+C jack. ABC is designed to mix audio signals, but can be modified to mix CV signals instead. There are 6 solder jumpers on the back side, which can be connected to turn the ABC mix into a CV mixer. Simple yet versatile: ABC mixes mono, stereo or CV signals. There are also 3 jumpers on the back side which can be used to normalize inputs A to D, B to E and C to F. This is useful if you would like to use the ABC mix as a 3 channel stereo mixer (using both outputs and having separate volume control for left and right channel). Check out videos here and here.

 

Features

• 6 channel mixer

• 6 inputs A,B,C,D,E,F

• 2 outputs A+B+C and D+E+F (A+B+C is mixed into D+E+F if no jack is inserted in A+B+C)

Bastl - Kompas

Probability Trigger Generator. Kompas is a three-coordinate probabilistic pattern navigator. Each coordinate has a unique travelling pace and a dedicated trigger output. The amount of probability can be adjusted manually or by external voltages. Once a coordinate has been adjusted, a new pattern is generated and looped until the next change of direction. This tool is the outcome of the environment we are in and is inspired by non-linear approach to music and life – don't build any expectations, choose your direction and discover new paths. Unlike common probability operation, instead of filtering a pre-determined sequence, Kompas uses probability to generate new looping patterns based on the direction you choose. Here is a video about Kompas.

 

Features

global clock and reset input

3 x 32 step pattern generators with travelling algorithms

3 CV inputs for coordinate modulation

3 trigger outputs

2/5/10ms selectable trigger length (via boot settings)

Bastl - Popcorn

Compact, but incredibly musical sequencer / quantizer / arpeggiator – you name it! Popcorn sequencer embraces the idea of making selection of 8 notes that can be browsed in many different ways. It all just depends on the signals you feed it with. It is incredibly musical when used with rhythm sequencer such as Knit Rider because it has two triggers A and B which will go 1, 2, 3, or 4 steps forward or backward depending on the settings of the dedicated knobs. You can also address the steps with CV or 3 binary gates. You can use CV to transpose the pitch or transpose it in a quantized way or change minor major settings of the quantizer with gate.

Bastl - Timber

Timber is very flexible wave shaping module that can produce rich timbres by adding harmonics to simple waveforms (triangles and sinewaves) or any other signal. It has 2 different unique wave shaping circuits, the WAVE DRIVER (I) and the WAVE FOLDER (II) and voltage controlled crossfader to fade between the different circuits or between one of them and the clean input signal. Here's a video and Soundcloud demos.

 

Novel take on the Serge style wavefolding circuit & more...

Both circuits share the same control voltages: the SHAPE which sets the input amplification before the wave shaping circuit and the SYMMETRY control which adds voltage offset to the input signal to provide various asymmetric overdrives or wave folding sounds. There is also voltage FBK CV jack which when provided with positive voltages feeds respective portion of the output signal back to the input which results in chaotic and aggressive behaviours. It is calibrated to work well with 5V gate voltages. The WAVE DRIVER (I) is an overdrive circuit with one folding stage and it has 2 configuration 3-way switches (9 different configurations). The drive switch can set the overdrive character to SOFT or HARD or something in between. The FOLD switch can set the folding threshold to HI or LO or it can turn the folding stage off in the NO position. The WAVE FOLDER (II) is a novel take on the serge style wavefolding circuit which has specific behaviour to abuse the high gain of the input amplification stage to provide rich high frequency timbres with higher settings of the SHAPE parameter. It has a configuration switch which can either activate clean 4 stage wavefolding in the OK position or highly asymmetric folding stage in the KO position that provides strange metallic character. The NO position provides only the very last overdrive-folding stage.

 

Features

WAVE DRIVER (I) is overdrive circuit with one folding stage.

3-way DRIVE SWITCH to set character of overdrive (SOFT-MID-HARD)

3-way FOLD SWITCH to configure the folding threshold level (LO-NO-HI)

independent output I. OUT

the WAVE FOLDER (II) is a 4 stage wavefolding circuit

3-way FOLD SWITCH to set character of folding stages (OK-NO-KO)

SHAPE sets input amplification before signal enters waveshaping stages

SYMMETRY adds voltage offset to the input signal

SYMMETRY becomes bipolar attenuator when the jack is connected

X-FADE voltage controlled crossfader with bipolar attenuator

switch to select between INPUT and I. WAVE DRIVER for the left side of the X-FADE

X-FADE IN jack breaks normalisation of II. WAVE FOLDER on the right side of X-FADE

Bastl - Tromsø

VCO, Comparator and Sample & Hold Combo. Tromsø is a combination of 3 basic utility modules: VCO, Comparator and Sample & Hold. Internal normalisation allows you to instantly use it as voltage controllable analog downsampler (or sample rate reducer if you like). The sample rate is set by VCO Rate and a sort of “dry/wet” mix effect which is achieved by adjusting the Threshold when in the Track & Hold mode. Checkout the video.

 

This architecture was inspired by a machine called Distortotron made in 1994 – arguably the first analog downsampler and bit distortion of its kind. That machine came from a collaboration between Norwegian musician Mental Overdrive based in Tromsø and the inventor group Psybe (Svein Berge and Henrik Sundt). It was created from a need to bring back oldschool sampler aliasing and lo-fi effects and heavily influenced the sound of album Plugged which is the landmark of the so called Tromsø sound.

 

The VCO of Tromsø module can track one volt per octave when the Attenuator on the FM input is fully open which makes it possible to have the downsampling effect track with the pitch of a played note. All 3 utility modules of Tromsø can also be used completely independently because the normalisation disappears once you plug a connector into the inputs.

 

Features

• Triangle core VCO

• Exponential FM input with Attenuator Knob

• Tracks volt per octave over about 5 octaves when attenuator is fully open

• Switch to change range of the VCO – high= 15Hz-45kHz, low=50s – 50Hz

• VCO output is normalised to Comparator Input thus Comparator Output creates pulse waveform for the VCO (Threshold = PWM)

• Comparator has Threshold Knob, CV Input for Threshold, Input and Output with indication LED

• S&H section has gate input, input and output

• Switch to select mode: Sample & Hold (samples at rising gate and then holds) or Track & Hold (at high gate tracks, at low gate holds)
