If you want to drive the Mini from a +15V gate, you need a simple one-transistor(NPN)-one-resistor circuit. Connect the collector to the S-TRIG signal input, the emitter to ground and a resistor of about 10K..100K to the base. The other end of the resistor is your +15V trigger input. Don't forget to connect the ground of the synth to the ground of the device driving it. I've used this circuit successfully with a sequencer delivering positive going gate pulses, and it has worked admirably. (Not much to fail really). Sadly, I don't have access to a Mini anymore... /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 -- "Radio-activity - It's in the air for you and me" -- From analogue-request@magnus.acs.ohio-state.edu Tue Mar 16 02:31:30 1993 Received: by quark.magnus.acs.ohio-state.edu (5.65/3.910213) id AA18223; Tue, 16 Mar 93 02:31:19 -0500 Errors-To: analogue-request@magnus.acs.ohio-state.edu Sender: analogue-request@magnus.acs.ohio-state.edu Received: from nic.lth.se by quark.magnus.acs.ohio-state.edu (5.65/3.910213) id AA18218; Tue, 16 Mar 93 02:31:17 -0500 Received: from axisab.axis.se by mail.lth.se with bsmtp (Smail3.1.28.1 #2) id m0nYW74-000MTuC; Tue, 16 Mar 93 08:31 MET Received: by axisab.axis.se (/\==/\ Smail3.1.25.1 #25.6) id ; Tue, 16 Mar 93 08:28 MET Message-Id: From: ricard@axis.se (Ricard Wolf) Date: Tue, 16 Mar 93 08:28:11 MET X-Mailer: Mail User's Shell (7.0.1 12/13/89) To: Chris Meyer Subject: Re: Building Minimoog -> problems...

On a similar note, I've heard that the wiring scheme inside the Mini does a lot as well. There are a lot of parallel wires between the front panel and the various (well, four then) circuit boards. /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 -- "Radio-activity - It's in the air for you and me" -- From analogue-request@magnus.acs.ohio-state.edu Mon Mar 15 12:54:12 1993 Received: by quark.magnus.acs.ohio-state.edu (5.65/3.910213) id AA17705; Mon, 15 Mar 93 12:54:02 -0500 Errors-To: analogue-request@magnus.acs.ohio-state.edu Sender: analogue-request@magnus.acs.ohio-state.edu Received: from nkosi.well.sf.ca.us by quark.magnus.acs.ohio-state.edu (5.65/3.910213) id AA17700; Mon, 15 Mar 93 12:54:01 -0500 Received: from well.sf.ca.us by nkosi.well.sf.ca.us (5.65c/SMI-4.1/nkosi-930216-1) id AA02085; Mon, 15 Mar 1993 09:51:39 -0800 Received: by well.sf.ca.us (5.65c/SMI-4.1/well-930216-1) id AA21470; Mon, 15 Mar 1993 09:50:09 -0800 Date: Mon, 15 Mar 1993 09:50:09 -0800 From: Chris Meyer Message-Id: <199303151750.AA21470@well.sf.ca.us> To: ANALOGUE@magnus.acs.ohio-state.edu, devans@snowhite.cis.uoguelph.ca Subject: Re: MiniMoog Release Date Status: OR 1965 would be way too early for the Mini - the first modular beasts were just in gestation back then. One piece of synth folklore is that Keith Emerson played a prototype of the first Mini on the first ELP album (y'all remember Lucky Man, don't you?). I'm not near my album collection right now, but '74 sounds right to me too. Oh, and another piece of folklore is that the Mini and Arp 2600 were both shown at the same AES show for the first time, so anyone who can date the 2600 would be on a good track as well. - CM From analogue-request@magnus.acs.ohio-state.edu Mon Mar 15 05:41:05 1993 Received: by quark.magnus.acs.ohio-state.edu (5.65/3.910213) id AA01314; Mon, 15 Mar 93 05:40:58 -0500 Errors-To: analogue-request@magnus.acs.ohio-state.edu Sender: analogue-request@magnus.acs.ohio-state.edu Received: from nic.lth.se by quark.magnus.acs.ohio-state.edu (5.65/3.910213) id AA01309; Mon, 15 Mar 93 05:40:56 -0500 Received: from axisab.axis.se by mail.lth.se with bsmtp (Smail3.1.28.1 #2) id m0nYCb8-000MTyC; Mon, 15 Mar 93 11:40 MET Received: by axisab.axis.se (/\==/\ Smail3.1.25.1 #25.6) id ; Mon, 15 Mar 93 11:34 MET Message-Id: From: ricard@axis.se (Ricard Wolf) Date: Mon, 15 Mar 93 11:34:16 MET X-Mailer: Mail User's Shell (7.0.1 12/13/89) To: Pekka Martikainen , analogue@magnus.acs.ohio-state.edu Subject: Re: Building Minimoog -> problems...

My suggestion: use BC549's for the NPN transistors and BC559's for the PNP. I don't thing the TIS97 (etc) was anything special, it must have been a common transistor at the time of building the Mini, since it is so common. I'd guess that the TIS-series was done by Texas Instruments, the gues who gave us TIP 41 and other power transistors. But note the small circled M for instance in the filter and vca: this indicates the transistors should be matched. /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 -- "Du har en ful hund" -- From analogue-request@magnus.acs.ohio-state.edu Mon Mar 15 04:41:13 1993 Received: by quark.magnus.acs.ohio-state.edu (5.65/3.910213) id AA00638; Mon, 15 Mar 93 04:41:03 -0500 Errors-To: analogue-request@magnus.acs.ohio-state.edu Sender: analogue-request@magnus.acs.ohio-state.edu Received: from cs.tut.fi by quark.magnus.acs.ohio-state.edu (5.65/3.910213) id AA00633; Mon, 15 Mar 93 04:41:00 -0500 Received: from kaarne.cs.tut.fi by cs.tut.fi with SMTP id AA07322 (5.65c/IDA-1.4.4 for ); Mon, 15 Mar 1993 11:40:55 +0200 Received: by kaarne.cs.tut.fi id AA18982 (5.65c/IDA-1.4.4 for analogue@magnus.acs.ohio-state.edu); Mon, 15 Mar 1993 11:40:54 +0200 From: Pekka Martikainen Message-Id: <199303150940.AA18982@kaarne.cs.tut.fi> Subject: Building Minimoog -> problems...
