When you play different notes, you get different pitches. But the VCA seems to stay at maximum all of the time: no envelopes.

So, actually, I can't tell if any part of the EG is OK. It's doubtful that the EG would fail; most likely something in the keyboard is stuck. This is easy to debug if you're at all good at electrical stuff (and near impossible if you're not). My take on the Arp, after an hour or so: it doesn't scream "Analog! I'm analog!" like the Minimoog, the sounds are somewhat thinner. Only 2 audio freq oscillators with fewer waveform choices, and the filter isn't as phat. But it's capable of more subtle and sinister sounds, and some way-out noise-mod things the Moog can't touch. Right. Also the sync'd VCO, sample-and-hold triggering on each note, the two-note polyphony, and some other really diabolical stuff make it a valuable machine. Also not sure if those multicolored blurps on the sliders are cute, or the ugliest thing I've ever seen on a production synth. Maybe both. Um, look closely, it's functional. The first VCO signals are blue, the second VCO signals are green, the envelope generator signals are red, the LFO signals are peach, and so forth. I think it's a great idea. -- Don From analogue-request@magnus.acs.ohio-state.edu Wed May 5 18:25:31 1993 Received: by quark.magnus.acs.ohio-state.edu (5.65/3.910213) id AA03356; Wed, 5 May 93 18:23:53 -0400 Errors-To: analogue-request@magnus.acs.ohio-state.edu Sender: analogue-request@magnus.acs.ohio-state.edu Received: from ACS.BU.EDU by quark.magnus.acs.ohio-state.edu (5.65/3.910213) id AA03351; Wed, 5 May 93 18:23:52 -0400 Received: by acs.bu.edu (5.61+++/AIX-3.2) id AA34187; Wed, 5 May 93 18:23:55 -0400 Date: Wed, 5 May 93 18:23:55 -0400 From: jdisegi@acs.bu.edu (Jonathan Disegi) Message-Id: <9305052223.AA34187@acs.bu.edu> To: analogue@magnus.acs.ohio-state.edu, rej@jerry.sal.wisc.edu Subject: Re: Hosed Arp Odyssey Status: OR This "infinate sustain" is one of the most chronic ARP problems I have ever seen, and it is due to blown/shorted/faulty capacitors that prevent the note from ever turning off. My OMNI had this problem when I first bought it (the string section never stopped playing). Luckly, I knew an electrical engineer that helped me fix it but it took us DAYS!!! If anyone ever has this problem, I have an OMNI service manual/scematics. I assume this is the same problem with the odyessy, but it could be something else as it employs monophonic voicing archatecture. Good luck!

I'm back from doing a thousand "Hail Moogs" after trying to start that 2-dimensional FM thread. What was I thinking? Anyhow, I know where there's this cute Arp Odyssey, and everything on it seems to work fine, except that there's no "note off"; it plays as if in infinite sustain. So, actually, I can't tell if any part of the EG is OK. Coincedentally, I was scanning r.m.m.s., and there's someone selling an Omni with the same problem ($150 if you're interested). So, is this a common malady that any of you have run across? And might it be easily fixed? My take on the Arp, after an hour or so: it doesn't scream "Analog! I'm analog!" like the Minimoog, the sounds are somewhat thinner. Only 2 audio freq oscillators with fewer waveform choices, and the filter isn't as phat. But it's capable of more subtle and sinister sounds, and some way-out noise-mod things the Moog can't touch. Still not sure if it has a place in my heart, but I'd give it a try. Also not sure if those multicolored blurps on the sliders are cute, or the ugliest thing I've ever seen on a production synth. Maybe both. -Randy
