Re: Priority Modules

The VCA will attenuate the signal using a controlling voltage. The envelope module generates the controlling voltage that will control the VCA. Another way to see this: imagine the VCA as a volume knob, and the envelope module as the hand that can raise or lower the knob. As the voltage from the en...

Re: Knob Potentiometer Feel

As usual, Dave Peck makes a really, really good point. That being, remote control of oft-used knobs . I would add that the control pot module need not be cheap. it can rather be a module with an expensive pot -or pots- that will stand up to intense and extensive use. As seen in good DJ mixers. Taki...

Re: Knob Potentiometer Feel

Tip: If these filter cutoff pots lost their original damped feel and developed a more 'loose' feel because you tend to give these pots a whole lot of use, doing manual filter sweeps etc., consider using some simple module that gives you a variable DC voltage output with it's own knob to control this...

Re: Semi-Modular with CV - recommendation?

One of the various 2600 type semi-modulars that have been recently released.

Unless you get lucky and find a Cwejman S1 mk2, which would be my first choice for a semi-modular, but almost impossible to find.

Have you seen this? There are various options besides the version shown here: https://www.ericasynths.lv/shop/eurorack-systems/techno-system/ Maybe swap out the 'bass line' module for something that does additional percussion stuff, like this: https://www.noiseengineering.us/shop/basimilus-iteritas-...

Re: KORG to Remake ARP Odyssey

The filter on the Odyssey already allows you to modulate it with negative or bipolar control voltages. The LFO and the S/H are both 'hard wired' to the filter as mod sources and they are both bipolar CV signals. A bipolar or negative CV into the filter via the pedal jack would not be any different.

Re: Feedback is your friend.

A tip: Have an inverter handy when doing these feedback experiments and try the feedback with and without inverting it. This can sometimes make the difference between a feedback path not doing anything interesting, and doing something awesome. For example, when feeding back the output of a 12dB/octa...

Re: Tuning Issues With Korg Arp Odyssey

On the original ODYs, there are two trims for the Up/Dn 2Oct switch. T3 and T4 on the A1 Bd. You can read abou them in the ARP Ody service manual. T2 is labeled "normal", and actually sets the down 2 oct position. T4 is for the up 2 oct position. The calibration for the Korg ODYs probably coincide ...

Re: Recommend Hardware Compressor

It's pushing the top of your budget but have you considered the Drawmer 1978 for right around $1k? It sounds excellent and has some unique features. Or for about $700, Warm Audio has a new SSL-style bus compressor. I haven't heard it, but I've been pretty impressed with their other stuff so far. Ver...

Re: Tuning Issues With Korg Arp Odyssey

Re: Strings and saw waves

The classic subtractive analog synth string sound doesn't require very complex or unusual patching. I created the "VA Strings" patch, with eight variations, in the Clavia G2 Modular's factory patch library. And that was done using a pretty plain vanilla patch with two or three oscs into a filter > V...

Re: Tuning Issues With Korg Arp Odyssey

It looks like the Korg is a little different from the original Arp Odyssey here - on the original, there's just one trim pot for the octave switch, and you just adjust it so that changing the switch position gives you exactly 2 octaves up & down (you do this AFTER you adjust the 1V/oct tracking in t...

Re: reverse engineer this sound picture

Assuming each line is depicting a separate waveform, it is comprised of lots of triangle waves tuned to integer intervals of the fundamental, and all hard sync'd to it at the zero crossing point. All waves are at the same amplitude. I've made a few patches inn a Nord Modular based on this idea, sort...

Yes, but HOW is your DAW routing these multiple signals to the various different destinations (i.e., s...
