On the "hold multiple sound buttons" subject
Quote
I wonder if there could be some sort of patch bay built for this, or a way to make the switches STAY on?
I paralleled each sound select button with a spdp switch as can be seen here:
http://www.electri-fire.com/bartsmit.htmMy Hing Hon EK-001's all had black blob circuits, I didn't even know there were versions with proper IC's. It makes no difference to their bendability, all connections are available at the Black Blob version as well. For this subject I adhere to the pin numbers from the elenco manual. On the blob versions you can trace the connections to the onboard switches easily. Many useful connections have jumper wires that you can connect to.
http://manuals.elenco.com/manuals/ak-900.pdfUseful pins for a patchbay: Switch matrix pins 1-2-3-4-5-6-7-66-67-68
Making a patchbay for "sound inter-mangle" would connect to pins 4-5-6-7 , patching them among themselves and to pin 1 and 68.
Remote change of rhythms: pins 4-5-6-7 to pin 66 and 67.
Rhythm pattern bends might include stop (pin 3 to 1) and start (pin 3 to 68)
Pin 2 to 4-5-6-7 gets single drum hits.
Also useful for rhythm bends pin 53 (tempo LED out). To connect to single drumhits, CMOS switch control, or to the envelope part of the signal with a depth pot, between R21 and R22 maybe. The tempo LED out is active LOW. May need an invertor for some applications.
In fact any signal could be added to the envelope signal, giving AM ringmod like effects with audio frequencies.
I'm into building CMOS circuits (or Lunetta's) nowadays. Lunetta's may include use of CMOS switches (like CD4016, 4066) or line selectors,aka multiplexors, (like CD 4051, 4052, 4053).
With these switches or multiplexers controlled by sequencers, CMOS logic or LFO's, bends can be sequenced, randomized or (indeed, you guessed it) LFO'ed.
I recommend the Lunetta forum at:

I need some time to digest this. So:
