More stupid synth tricks...

[gstopp at fibermux.com]

     Okay guys forgive me but I just have to say this.....
     
     I think that this is an example of EXACTLY the kind of "new explorer" 
     attitude that keeps DIY electronic music evolving! I've watched Chris 
     List (hi Chris!) start out as a newbie with nothing but questions, and 
     now he's out in front building A/D flash converters to front-end his 
     home-brew sequencer fer chrissakes! Man he's got the bug, big time. 
     Watch out for this guy! That other post on AH about DIY stuff was a 
     good one too.... I think you *should* get an award for soldering your 
     300th 100K resistor!
     
     Well I've been away from the project bench for a long time - we just 
     bought a new house so finding my *pants* in the morning is a 
     challenge, let alone the soldering iron. Messing with DIY projects at 
     a time when the cars won't even fit in the garage would be suicidal. 
     This of course is frustrating to me because guys like Chris and Matt 
     and Ric are really doing some inspiring stuff.
     
     Anyway just wanted to say "keep it up guys".

Howdy DIYers,
     
Well, I've just <finally> finished the "Program Select" input on my sequencer. 
This is a CV input which goes through an A-D converter and makes the sequencer 
jump to one of it's 16 steps (based on a 0-5v input). 
     .

On another front, Matt and I worked out some enhancements to that AD + AR 
circuit I told you guys about last week. I just built one of these "enhanced" 
versions last night and it works great! I added a switch that lets it work 
either the way it was originally, **or** as a pure linear slew limiter with 
different CV-able rates for rise and fall. This was a little tricky because the 
original schem only responded to a positive input and I wanted the slew lim to 
be able to work over the + and - voltages...
     
I also got the min. decay time closer to the min. attack time.
     
I will be updating my schematics and posting them on the Web somewhere... 
(calling Ric Miller - you interested in this one?)
     
(BTW, there were some errors in the first schem I sent to a bunch of people. 
For one, I mixed up the inputs to the flip-flop in the translation from my 
notes to a computer-drawn schem - there's other stuff. Wait for the updates 
before you start building!)
