Feedback Modules - ENV-310

only 2 left

This is an envelope generator based on the SMD AS3310. The AS3310 is a modern recreation of the classic Curtis CEM3310 chip, used in many famous mono and poly analogue synth from the eighties. We took the best ideas from all the classic 3310 circuits and tried to squeeze the maximum from this fantastic chip. The MODE switch takes this module beyond a simple ADSR type envelope generator.It can work as:• NORMAL - a conventional ADSR envelope,• DAMPED - an ADRR piano envelope approximation• AUTO - a short gate will cycle the envelope shaper through a complete ADR envelopeIt has an additional TRIGGER input which can be used for generating multiple peak envelopes.Features:• 4 control pots:Attack, Decay, Sustain, Release• 1 gate switch: triggers ADSR cycle• 1 mode switch: Normal (ADSR),Damp (ADRR),Auto (ASR)• 1re trigger input• standard 10 pin euro power (+12V / -12V)DIY-Kit-Type:SMD-Kit-2.

Feedback Modules - ENVF

only 1 left

This is an envelope follower based on a classic module from the seventies but with some improvements to suit modern needs.The IN signal is routed to the envelope follower circuit and also to a THRU output, so the original signal is also available for external processing.The envelope follower has three controls, a switch to select response time (fast, medium, slow), a pot to adjust GATE threshold and a pot to adjust the envelope CV level.This little module will help you shape the timbre and/or the level envelopes of your sounds. From dynamic envelope filtering to compressor like side chaining there are lots of possibilities to mangle your audio.DIY-Kit-Type:THT-Kit-1. This is a Do-It-Yourself kit, not an assembled module.
