Re: looking for a DIY stereo mixer with VC panning

Some interesting suggestions. The L-1 looks very good, in fact too good TBH, but a bit too polished and expensive for a DIY project (gold plated PCB, rear panels, etc.), I'm looking for something a bit more 'ghetto' that has the same basic functionality. Surprised there isn't more stereo mixers with...

Re: looking for a DIY mixer with VC panning

It will work standalone. The mix expander is designed to take +12v, -12v, ground and 8 gates from the turing machine. However, without the turing machine, you can instead supply the power directly from your case rails and use gates or other CV in place of the gates from nearly any source - LFOs, co...

I just made a simple turing mix expander "deexpander" on stripboard that accomplishes this, so you have cv over panning for four inputs. Lmk if you would like pics.
Sounds interesting, would I need to build a Turing machine for this, or will it work as standalone?

looking for a DIY stereo mixer with VC panning

I've looked around the usual places for a DIY eurorack audio mixer that allows voltage controlled panning & level to no avail. Something in the region of 4 CH would be ideal. Does such a thing exist in the DIY realm? I'm really looking for a PCB/panel combo, I'd prefer not to buy a kit as I have hug...

Re: a legend is back...System-700 in eurorack

Looks like Synthcube only have kits, which is ok for beginners who don't have a stock of parts, but like most I prefer to buy PCB/Panel sets as I have a good stock of parts and can't justify spending 5 times the price to buy parts I've already invested in. Besides I'm in the uk, so I'd have shipping...

Bending a Behrnger RD 8

I'm in the process of modifying a Behringer RD-8, which I recently posted about. I've managed to get all the mods sounding really nice, but after I'd put it back together I realised the wave designer is not working... If I switch all the sends from all the instruments on, it plays quietly (I'm guess...

Re: a legend is back...System-700 in eurorack

I'm guessing that sequencer is a dead hope. I was just on the Pharmasonic site, looks like the sequencer has been pulled, and no sign of the 715 filter either. Has anyone received any other orders from Pharmasonic recently? I'm a little reluctant to make any orders just now if everything is halted.

Looking for a transistor...

During my exploration of the Behringer RD 8 PCB, I was pobing for mods, and managed to set the magic smoke free from a SMD transistor labelled T11 (next to the BD tuning pot). All that's left on the surface of the package is '33', there is a similar looking 33 on a nearby transistor, so I'm guessing...

The square pad is negative on these so electrolytic caps look good. Pinout looks correct on transistor pair. The right header connection looks like it might have a short between the bottom two pins.
It was indeed a short on the header. Well spotted, thank you!

Great sounding filter!

Timo Rozendal Steiner Parker filter, help needed

Hi, I have finished building the Steiner Parker filter by Timo Rozendal. It passes audio, but I cannot seem to make it do anything not from the panel pots or the trimmers - ie. the filter is fixed fully open. Resonance appears to go into self oscillation when turned fully clockwise, but it's hard to...

It's been crickets since I sent them hundreds of dollars in October to pre-order two of these sequencers. The announced mid-November ship date came and went nearly a half year ago now. There have been no updates from Pharmasonic about it that I've seen (and I've been looking!), although they seem t...

I recently saw an advert for a 1978 MS20 with the OTA filter. I'm sure it was a mistake, but got me thinking, what year did Korg change the MS20 filter? I have an MS10 and MS20, both with Korg 35 filters, they also have dark grey panels rather than the black on the later models. Did they change the ...

I'm running two PSU's in my system. When it comes to wiring your modules, separate oscillators and filters to one PSU, and LFO's & modulation sources to the other... You'll save yourself the headache of LFO / modulation pulldown on your oscillators & filters.

"modulars" is a loose term, specify... If you're powering a 5U MOTM system with +/-15VDC then it's fine, put it into a eurorack which expects +12/-12/+5VDC and you would run into problems, potentially damaging modules by overpowering. Specify which system you're looking to power. The chart at the bo...

your switch most likely has a bad internal connection, or there is a bad solder joint to the resistor chain at that point. measure the voltage at each point along the switch contacts. if the 8' contact is 0V at the switch, then there is a bad solder joint or broken trace. if its 2V, then there is a...
