"This unit has just been serviced and modded, in which it received the following:
- new power cord
- complete recap
- Filter Cutoff and Resonance mod for Brass (left 2 knobs)
- Percussive envelope Decay/Release switch and knob (the knob adjusts the decay of the Piano and also the Strings when in Percussive mode, and the switch turns off the envelope re-trigger circuit when NOT in percussive mode - which is useful for layering pad sounds with the Strings)"
"Envelope Generator and Formant Filter are made with Max (Serge Env. Generator Gen~ Code by Bertrand Fraysse). Envelope to CV to Buchla 292c (LPG) and inverted/attenuated to Buchla 158 (VCO) Frequency. LoPassGate Out to Formant Filter."
"Wow, just wow, this this is ACE! That said what would you expect from AJH Synth. Amazing sounding analogue is there forte. So here is the AJH Synth Gemini 2412 (you can patch one 12dB filter to the other for a 24dB filter should you wish) Dual Vintage State Variable Filters module for Eurorack modular synths. I won't dive to far into details here as you can just watch the video! Check out the timing index / links below to skip around the video.
TIMING INDEX (note ... there's cross over between what happens in each patch with plenty of sweet spots and tips but this will get you around the video should you wish to skip around)
