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 envelope
It has an additional TRIGGER input which can be used for generating multiple peak envelopes.

• 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)

Power:  55mA @+12V; 16mA @-12V

HI-FUSION is a remake of the classic Polyfusion from the 70s with some improvements.
It is a low pass OTA VCF based on the well known LM13700 ic.
We chose to make this circuit because it's v/oct stable, and the trimmers allow to calibrate it properly.
It has a switch for 2 pole and 4 pole configuration, each with it's own character and timbre.
This design produces nice sounding filter fm results.

This kit contains all the parts needed to build a complete HI-FUSION module.

• 1 audio input: IN
