For the moment, I am doing a standard 4 stage +initial delay and optional manual gate time, with CV control of ADSR as well as exp-lin-log adjustment on ADR. You have to start somewhere and that is exactly what this design is - a start. Giant monster EGs have been put on hold unt
2006-10-18 by hitchindave
FWIW, CV control of rates + levels would be very cool... With something like the programmer, different envelopes could be very easily applied during a piece, as well as continously variable parameters. I can see a lot of fun to be had there.... How many stages are you aiming at,

hi I have a on-on SPDT switch wired to switch-tab of the jack. if you patch a gate signal into the jack, the switch will be disabled. wire the outer pins of the switch to +V and ground, center pin to the jack. you could just leave off the jack, if you are short on panel space, an

Ken, So, I've heard, you are going to be making an envelope generator? This would be just what the doctor ordered. Cole
2006-10-17 by Pete
A new envelope generator?! Whoo hoo. Like Jason said, I pretty much only be buy CGS modules. Everything else is just too expensive. My modular is quickly looking more like a CGS modular than anything else. Though I do have some other stuff non CGS. I recently built three Thomas H

Ken, I just tried this. I ran the gate signal to the gate input and trigger input of the ADSR. It still is not retriggering the envelope like it should. I need to completely let go of each key to have the envelope restart. I will check and see if I wired the trigger input incorre

If you want an even finer tune pot, add another 100k pot, with one end to +15 and the other end to -15. To the wiper connect a 4M7 resistor. Connect the other end of the 4M7 resistor to the CVSN pad. Ken >On the schematic and connections diagram, I only see a place for one >"Tune

2006-10-11 by Richard Brewster
Wait a minute. The PWM input does not need to be connected up. The 100K resistor to ground from the - input of the comparator sets the detection point to zero. And the AC-coupled sawtooth wave going to the + input of the comparator centers the waveform around ground. So without a

Ahh. I think I'm starting to understand. The PWM can be connected to a pot to set the width of the pulse? Is that what you are saying? And without this, the pulse width would be so thin, that there's no noise? How would I wire a pot to the PWM? I'm thinking the PWM to the wiper o

2006-10-11 by sasami@hotkey.net.au
1) Use a different VCO output. The square wave likes the PWM input to be connected. 2) Sweep the tune knob, and if you still don't hear anything , try adjusting the SPAN and ZERO trimmers. This VCO can quite happily work well above the hearing range if these are wrong. Ken >Hello

I thought all the BOMs on my website used 1% 1/2W Metal Film from the MSR25 Series by Phoenix. If you can point to where I refer to 1/4W that would be appreciated. Most synth circuits will work with 1/4W resistors without any problems. There are a few exceptions most often where

2006-09-26 by Richard Brewster
You can get 1% 1/4watt resistors from Mouser.com quite cheap, and if you intend to do a lot of building it pays to buy 200 quantity for $4.00 US. That is 2 cents apiece. Are your 0,6w resistors cheaper than that? If those are 10% tolerance I would stay away. You want at least a 5
