Make Acid With... A Siel Expander 80 synth module

Published on Dec 8, 2015 BEATS N BOBS

"This unloved, little known synth has a nice meaty SSM filter in. Same as Prophet V, Kawai K3, Korg Mono Poly. It has square and saw plus noise, double mode., detune, two Lfos, Two VCO ENVs and seperate filter ENV plus Chorus and Square wave extra octave (drawbars) waves. Plus you can change everything via MIDI CC. So I must be able to get a nice Acid bass line surely?

Well after some tweaking with a resistor, I got the resonance right up. Its a shame theres no Glide or portameto but it DOES have dynamics for AMP and Filter so This can be used as accent via velocity sensitivity which I can adjust later. I also try adding pitch bend for a fake glide. Its not great. So later I added a delayed VCO LFO modulation just at the tail end of long notes. I also show a pad sound with keyboard tracking on the filter and LFO on the filter. Nice but LFO is not too slow.
I used Ableton to send CC commands within a pattern a I can use shorter or longer lengths loops on the CC .
Some parts I add some distortion and echos but thats it."
