From my limited knowledge your are absolutely right, it's primarily a problem with the inputs. This problem can be remedied with buffered mults however.

I had problems with my .com when for example triggering several EG's and sample and holds off of the same oscillators square output. If you have the time to test it I would most appreciate it. But really, no need as I probably won't have enough modules for it to be a problem, at least not in the beginning.

ah you don't get off that easy. lol. tell me an exact patch and i will do it. as i said, i never have any difficulty. there is also the concept that there are actually different behaviors within the modules by design. for eg, eg's from the quad eg can all be trig'd from a simple single trig in. also i don't have any dedicated s/h but i do have three quantizers. you get the point.

Hehe, ok 8_)

So how'bout this:

3VCO square out mixed to just one VCO split to two eg inputs and both quantizers clock input. That should draw enough current to show if there are any problems, at least that is about what I had going in my .com when the problems showed up.

i assume you mean for the 3vco to be in lfo range if you want to use it as a clock? and if so, wouldn't you rather use one of the many dedicated clocks as opposed to using such a glorious audio source for such a simple task?

Just joining the thread here.

Jealous of all the Modcan B action.

I used to have a small Modcan B effects setup (digital delay, flanger, spring reverb, joystick) and I loved it dearly and I still miss it sometimes, but I just couldn't quite justify the space it took up and the expense tied up in it, so I sold it off and moved on to other things.

I'm hoping that the upcoming MOTM e550 digital looping delay will replace some of the functionality of the 59B.

Yes absolutely, this was just an example and I was unsure about what modules you had available. Couldn't remember you had a clock in there. Of course an LFO could be put to the same use 8_) Case in point though is, if I get things properly, that a clock or similar should be split and expected to drive a number of clock inputs.

i will check it out tonight if i get a chance. the comparator thresholds seem fairly easy to tickle on everything. it will be interesting to see if i can get something to fail.

ok, i took a break from dissecting legal babble and simultaneously writing a paper relating arguments of why socrates couldn't in philosophical good conscience escape from being put to death...to do the mult test. my goal was to make the system fail. or find enough trig/gate inputs that at some point the voltage droop would reach a point that the gate/trig ins would not observe a change of state. i could not get that to happen. i set up two different experiments. one with a digital clock as the source and one with an analog clock and always a miniwave in at the end to measure the voltage level after tricking all the comparators simultaneously. in both cases i had 10 count em 10 gate/trig ins going plus the MW cv in at the end. it worked each time. no problems whatsoever. the miniwave seemed to measure a full +5v at the end of the analog clock chain. the digital one was harder to discern. the clock i used was from the cv recorder gate out which is actually a very short trig so it is hard to actually measure the exact voltage level with the miniwave at the end but i am sure it reached above 4v if not the full 5v. it moves so quickly that the visual led representation is hard to use as a scientific indicator. i didn't take video because there was no sound and it was just a bunch of boring sync'd blinkenlightsâ„¢..and i am super busy right now.

so... not even vaguely significant voltage droop to speak of in either case. the only other set of tests which i think would be interesting would be to get a ton of vco's tracking 1v/o from a single 1v/o pitch info source (multed of course). i only have three 1v/o things atm and i know for a fact i can get them all to track together because i have done it. but maybe someone with way more vco's can try that one out.

the bottom line is that droop ain't no problem here and i believe bruce knows (and of course successfully designed) this to be the case as you can see in his line that he does not offer a buffered mult as one of his many many module designs for sale.

Great Liam, thanks a ton for taking your time to think, patch, investigate and write about all this! :tu: :hail: :hail:

i am about to patch up my vcos to try and get droop to occur. lol. glad to be of help! then off to sleep. talk to you in the morning!!! super excited about that.
