Re: Sequential Circuits Drumtraks front panel controls dead

The thing I would check first, you don't have the equipment to test. See if you can borrow a multimeter that has a frequency counter onboard. Assuming the thing uses a crystal oscillator to generate the digital clock, I would measure across the crystal pins to see if in fact the clock was working. N...

Re: New future retro product

http://future-retro.com/dboverview.html Now folks, most of my background in electronics is working with/repair/modifying/and building-from-scratch high-end audio gear (anyone else ever worked on a $12,000 CD player?). THIS is how you build a piece of gear!: http://future-retro.com/images/dblarge6.j...

Re: Fixing a broken JX-3P

Did a thorough inspection of the panel board today and didn't find any broken traces. The board is clean and appears to be in very, very good condition. I'm thinking that whatever caused the minor dents in the case isn't the reason why this JX-3P is broken. I've concluded for the moment that the th...

Re: What's ok to use as synth speakers?

That's just hi-fi nutjob talk. It is definitely possible to mix something so that it sounds the same on various systems. I've worked in a Munro room, and a domestic room that was very well acoustically treated. Absolutely wonderful to mix in, and to hear your favourite albums in. You immediately ex...

Re: What's ok to use as synth speakers?

If you just want to play and have fun listening to the sound of the music, almost anything will do (including computer speakers, providing they don't come from the Dollar Store). I simply use some Roland's Microcube suspended from my ceiling, and it fits my needs: affordable, sturdy, polyvalent, an...

Re: Jupiter 4 Preset Errors

This may be of some use to you: http://i46.tinypic.com/289eddu.jpg I don't really understand how this helps. I get that the presets are just set voltages throughout each parameter but I don't understand how I can get this fixed. Would you suggest a recap or something? Will i need a new CPU? If you ...

Re: Triggering an OB-Xa via MIDI pedals

As far as I know, the Encore OB-Xa midi retrofit is no longer available, as it can't be ordered from the Encore website. Kenton still makes one, but it will set you back about $450.00

Re: Juno 60 acting weird

Wait a minute, yeah, in a Roland, just scraping and vacuuming the foam away should work. For a minute there I had forgotten that the type of foam Roland used dries out, becomes brittle, and crumbles away, as opposed to the foam that Moog used that turns into, well, really nasty sticky goo. The dead ...

Re: Juno 60 acting weird

That foam is deadly for switches and sliders, because it's hard to dissolve, is sticky and gets everywhere. I would be trying to find out what's a good solvent and putting the whole thing in a bath of it. Don't forget to replace the lubricant in the sliders. Life's too short for opening up sliders ...

Re: Ridiculous eBay 'Buy-it-now' and starting bids.

I might be wrong, but $350.00 for an OB-8 voice card with NO CEM chips at all?

Re: Alpha Juno-2: Problems re-loading factory patches

Another crazy thing to check, because I just went through this same problem with an Oberheim OB-Xa: The factory patches are an audio file. It can be saved as a .wav, .aif. or .mp3. However, played through a computer, or CD/mp3 player, it may need to have the polarity of the signal inverted for it to...
