Ana Modulation Multiplier

video upload by Mystic Circuits

"Another quick patch showing off Ana's many capabilities. This patch shows how to use Ana to turn a single modulation source into multiple modulation signals and control your entire patch with the turn of a knob. Ana is incredible for feedback patching and unlocking the full potential of modules that provide their own modulation signals for self-patching.

This is a much longer demo because I have been having a lot of fun with this module combo as I have been beta testing the Entropic Loops Grackle, an innovative phase modulation oscillator from a new company that is a collaboration of Naomi from Omi Industries and genius programmer Eris. If you would like to know more about this module there will be some information posted to their website soon:

Frap Tools - System 1

"Today I'm having fun with a small dedicated Frap Tools system. It's a good opportunity to dive into what makes "West Coast" synthesis is and how it work. I'm also going to try to make it jungle (or IDM or whatever you want to call it) and then I'll show you some classic 'west coast' patch I love.

Have fun!"

These are CRAZY! ALL of the hidden waveforms on the Ensoniq ESQ-1

video upload by CGMAGIK

"I got the EPROM for the ESQ-1 that enables you to access the hidden waveforms 33-255. A small handful of them are pretty normal sounding, but the majority are really quite amazingly insane. It's like a broken ATARI 2600 or something. It gives the Ensoniq a strange 8-bit game console sampler kind of vibe. I'm looking forward to making some interesting and unique patches using some of these.

Watch at your own risk. Haha. It's an epic journey through some not very chill and friendly sounds."

video upload by Dr. Synthy Pants

"Electric-soul, tone-shadows,
Whispers of magic where circuits breathe deep.

What mysteries hum in the ESQ-1's core?

Wave-whispers, tone-shivers,
Hands explore, shaping the unseen into sound.

OSCILLATE
SHAPE
TRANSFORM

A hidden voice rises from circuits deep,
and my heart sings, alive and unbound."
