Here is a tune I just finished with the Klee. All the drums are coming from my diy drum machine. The event generator I built not to long ago is triggering all the drum sounds except the kick. The klee is triggering the kick. The event generator's internal clock is driving the Klee. The Klee is driving three XR2206 VCO's, two MOTM EG's, one VCA-1, and the 3320 filter. I am only using register B!
I also used a Space Echo 201, a Lexicon MPX-100 and my Mackie 1604 mixer. There is a lot of post processing. Compression, EQ, Flanging (waves plugins).

Update, I moved the tune to the, "A collection of Klee musics" thread.

Much fun to listen to! Very "drummy". Keep it coming! _________________ Garret: It's so retro.

The simplest way to move the attachment it to delete it and repost to the other topic. Not elegant, but it works. _________________ --Howard

Oh I forgot to mention that my Klee's trigger outputs will not trigger my CGS drum modules, the Cynare, and the dual chime. I think the gate outputs didn't work on the CGS stuff either. Do I have to adjust resistor values on my Klee to accommodate the CGS stuff?

Which range are your trigger outputs, 5 or 10V?
It's interesting - IIRC, I had 5V outputs on the BB, but it still triggered the Cynare (I don't have the other modules you mention). _________________ My Site

Okee doke - the drum module (which I have, too, forgot to mention) and the chime simulator should trigger on anything above 3V. The Cynare should trigger on anything above 2V. In fact, if you look at the Cynare schematic, you might notice it has a 100K/15K divider as a reference to the input comparator, just like the Klee (mosc needs to invent an innocent "whistling" icon ).
I'm fairly certain I ran both the Cynare and drum module off of 5V on breadboard Klee, but, being on breadboard, it's possible the flavor of the day could have been different. In any case, both trigger on my Klee, which has the 10V range outputs.
Just to be sure it's not a case of trigger width as opposed to level - you can double-check that by plugging a gate output to the trigger inputs of the modules - it looks like each of those modules has an input cap to turn whatever is presented to them into a pulse.
I know you mentioned that you may have tried the gates, but the gate width will vary with the clock - to remove that as a consideration, you can manually step the Klee by pressing the manual step switch. I designed that so the gates would stay high as long as they switch was pressed. The gate bus LEDs will stay high as long as that switch is pressed (of course, as long as a gate is progammed for the current step on a particular bus), meaning that the gate outputs are held high. The results of that would confirm or deny that pulse width is a concern here.
As an aside, the manual step switch is a way you can merge gates "on the fly", (even the master gate bus!) though each time you press it, it will step the sequence up one step.

Ok just checked and it seems that they do work with the trigger outs. Whats not working is the trigger input to the Cynare. If I take the trigger out from the Klee and plug it into the sustain input on the Cynare, it works. I setup the Klee to output 5v gates and triggers. I know the Cynare trigger input works, cuz I have been using it with my event generator just fine. _________________ Check out my music

My brain's probably distorted right now, but I can't see any way for the Sustain input of the Cynare to actually trigger it. It goes high when there's a gate signal (something greater than 2V), but there's a blocking diode in place so that it doesn't make it through to the trigger portion. What it does is allow the damper control to have an effect on the decay - if it's high, the envelope cannot discharge through the damper, so the decay will be longer than if there were not a gate signal present (under normal circumstances).
I'm sure you know this already, but this is why Ken states:
Quote:
Note: if the damper decay rate is set to minimum, and the sustain input is below about 2V, the envelope will be set at minimum, with the decay control having very little effect, so if you do not wish to use the sustain input, the damper decay rate should be turned to maximum.
I'll whip out the Cynare board when I get home and give it a whirl to see if anything pops up - I'll cut my levels down to 5V range to emulate what you're experiencing.
That is, if I have power when I get home - we're expecting an ice storm here.
I'll let you know what I find out. If I have power.

Well, I tried out my Cynare - mine triggered OK with the Klee trigger outputs. I rigged up a 100K pot and reduced the trigger output from the Klee - the Cynare stopped triggering at right around +2V. I thought I'd try putting the triggers into the sustain input to see what happened, but it wouldn't trigger off of those. It's a headscratcher!

Well it appears that the replacement CD4034 for register B has gone bad! Luckily I bought two of them so I just put the second one in there and its working. Even though my Klee is working fine now, I cant let it slide without figuring out why these chips keep going bad in register B. Can someone shed some light on why they keep going bad? Could it be bad grounding?

I'm not sure what could cause it - which manufacturer was it (TI or ...?).
Was the failure mode the same as before?
As an aside, I patched up my Klee just last weekend - first time I'd actually played the modular since right before Christmas. The Klee has been on, though, for most of the time, though - it's on the same powerstrip as my DW6K and SH-201.
I've been syncing it to MIDI through a MAP MTS-100. _________________ My Site

Your Klee has been turned on since Christmas!? Wow. Can leaving gear on for that long be bad? So the first symptoms I noticed, was that the Register B cv outs where not working. Then I noticed that the 8*16 switch was not working. Eventually the register B LED's would all stay on, and then the Klee just locked up. These are the similar problems that I had before. The first chip was the one I got from Bill, and the second one was from TI. I need to buy a few more just in case. _________________ Check out my music
