Re: Where can I find MOTM to Synthesizer.com power converter?

The only MOTM module I know of that ever used the digital ground was the MOTM-650 MIDI interface.

Re: Your surprised-you-module(s)

I'll toss in a module that doesn't get mentioned very much... the Dotcom Q128 A/B switch. A seemingly simple little module. Something devious I discovered: Mult a seqquencer's clock and feed it into a clock divider. Then choose, say, the divide-by-3 output and feed that to the control input of a Q12...

For a while, Doug/SSL was doing conversions of Jones O'Scopes to MU. Maybe if enough people were interested, he'd do some more.

Re: Polyphony/legato sense check (and hello)

The Roland Juno-106 has a voice allocation mode in which you can tell the synth which voice to allocate to which note by slightly arpeggiating each chord. The way it works is that the first note played is always assigned to voice 1. While you hold that down, the next note will be assigned to voice 2...

Re: Why does a square waves sound detuned when in the lower range ?

How loud were you listening to it? Volume has a little bit of an effect on the perception of pitch. Particularly with bass tone, low volume makes it difficult for the ear to determine pitch.

Re: BEGINNERS - What have you always found to be poorly explained?

One thing that I find confuses a lot of beginners is what a VCA actually is. A lot of integrated synths blur the distinction between a VCA and an envelope generator. The key points: (1) Most oscillators oscillate all the time, not just when you play a note. (2) An envelope generator produces a contr...

Re: sawtooth (not ramp) from pulse or squarewave wave - electronic basic

"The problem with this arrangement is that as the frequency of the square wave increases, the capcitor will have less time to charge, so the output amplitude of the sawtooth will decrease.

Re: sawtooth (not ramp) from pulse or squarewave wave - electronic basic

EDIT: related question --- in a DCO, is the digital part just the source of the pulse wave, or is the control over the charging time also digital (I assumed the latter)? It depends on the design. But in the Roland Juno-106, a DCO synth that most people have heard, the charging (ramp) control is ana...

Re: Harmonic Series

I've done some additive synthesis. IMO it's a synthesis method that is better done in software. You'd need a rather large system full of VCOs, LFOs, EG, VCAs and mixers to duplicate what you can do with a fairly basic additive plug-in like Minky Starshine (one of my most-used plug-ins). It is, howev...

Re: patching 5u to Euro, power precautions?

Not sure that's really necessary. If you're worried about the possibility that someone's synth has a line-to-ground fault that somehow hasn't blown up their synth, bring a power strip with you that has GFCI (RCD) protection, and plug your synth and their synth into it. This also ensures that both of...

Re: How do I choo-choo? (negative microtiming, Walschaerts))

You can do this sort of thing with any sequencer that has multiple rows and can be clocked by an external VCO. The trick is that you use one row to modulate the VCO frequency; send its output to a control input of the VCO and set the values on that row to speed up or slow down the VCO as needed.

Since this was posted in General Discussion, I'm assuming that input from the 5U community is being sought too.
