If it's all the way up, you will get infinite sustain. If it's this, turn the slider down and turn up the slider below the Voltage controller amplifier block and set the switch below it to AR or ADSR.

So, actually, I can't tell if any part of the EG is OK. This may be obvious, but the VCA GAIN control sets the base level for the VCA, and the EG is added on top of that, if I remember correctly (haven't used my Oddyssey for some time). It's easy to thing that the knob sets the amount of EG, i.e. the overall level of the VCA.

And might > it be easily fixed? I had a problem a few years ago with my Odyssey, where most of the contacts between boards had oxidized, so nothing worked properly. All modules seemed to influence each other. Solution? I replaced most connectors with good old-fashioned solder joints (the connectors didn't look too reliable).

I find the ADSR EG a bit 'sloppy': you can't get really short attack and decay times, so 'spikey' sounds are out. > 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. The knobs on my sliders began deteriorating when I got the machine, so I removed them all, leaving a short white stump belonging to the potentiometers themselves, but it looks better, and I don't have to worry about the knobs falling off. The pressure pads on mine have gone more or less completely ... stand a truck on them and they might react... anyone have any ideas of replacements? I saw a pressure-sensor based on conductive foam in an electronics magazine a long time ago, anyone tried any of these? /Ricard -- Ricard Wolf / | \ / | /- email: ricard@axis.se Axis Communications AB /__| \/ | \__ uucp: axisab.se!ricard S - 223 70 LUND / | /\ | \ Tel: +46 46 19 18 63 SWEDEN / | / \ | \__/ Fax: +46 46 13 61 30 -- "Welcome to - New Anger" -- From analogue-request@magnus.acs.ohio-state.edu Tue May 4 13:16:27 1993 Received: by quark.magnus.acs.ohio-state.edu (5.65/3.910213) id AA16261; Tue, 4 May 93 13:12:09 -0400 Errors-To: analogue-request@magnus.acs.ohio-state.edu Sender: analogue-request@magnus.acs.ohio-state.edu Received: from ncar.ucar.edu by quark.magnus.acs.ohio-state.edu (5.65/3.910213) id AA16249; Tue, 4 May 93 13:12:05 -0400 Received: from stout.atd.ucar.edu by ncar.ucar.EDU (5.65/ NCAR Central Post Office 03/11/93) id AA02886; Tue, 4 May 93 11:12:01 MDT Message-Id: <9305041711.AA21962@stout.atd.ucar.EDU> Received: from barleywine.atd.ucar.edu by stout.atd.ucar.EDU (5.65/ NCAR Mail Server 04/10/90) id AA21962; Tue, 4 May 93 11:11:59 MDT To: analogue@magnus.acs.ohio-state.edu Subject: Odyssey filter Date: Tue, 04 May 1993 11:11:58 -0600 From: Forrest Cook Status: OR Chris Meyer writes: >There was a rumor awhile back that Arp ripped off Moog's filter design >down the road and tried to conceal it by sealing the module in epoxy >"for temperature stability." When someone here mentioned an epoxy-sealed >filter, I began to wonder... I doubt that the epoxy was to conceal ARP ripping off Moog, it was probably to keep somebody else from ripping off the ARP filter design. I did read that there is an epoxy solvent out there that can be used to dissolve such modules and reveal the innards for the curious. It probably also removes the paint from the parts, so one would have to disassemble the pieces and measure the values to reverse engineer such a circuit. Probably not worth it for something so old unless it's for a repair.
