Sequential Circuits Split 8

Title link takes you to shtos via this auction.

"he Sequential Split 8 is Japanese produced analog synth marketed by Sequential Circuits. It is very similar in voice architecture and sound to the MultiTrak and SixTrak. All of these synths as well as the Akai AX 60 use one Curtis SENTE (CEM 3394) chip per voice. The Split 8 has eight voices where as the others mentioned above only have 6. The Split 8 seems to be designed for more use as a traditional analog poly synth like the Prophet 5 than as an analog workstation like the SixtTrak and MultiTrak. The Split 8 is capable of doing splits and layers and this is really its strength. As it has 8 voices, you can double up the oscilators and still have 4 note polyphony! By creating a split you can basically have a 4 voice synth with two oscilators per voice that can be detune really thickening up your pads. In split mode the Split 8 is also capable of Poly Mod like the Prophet 5 which uses once voice in the stack to modulate the other. Neither the SixTrak or MultiTrak have this ability. The Split 8 can also stack up all 8 voices to have one massive monosynth; great for supper thick leads and weighty basses!"

Dead Presidents Society

"The Dead Presidents Society is a group of friends who share a passion for the influence of technology on music, and who meet every Thursday morning at a coffee house in Berkeley, California. The group's name was born out of the fact that a number of the members were formerly presidents of electronic music product companies that died. :)"

Ben Pringle (The Rentals) Repairs the Pro-One


YouTube via TheRentalsDotCom. Sent my way via Sean.
"a quick "how-to" on fixing a problematic key or two on the Sequential Circuits Pro-One"
Note there is also a j-wire version of the Pro-One. I picked one up for $125 due to a sticky note. I popped it open, bent the j-wire back in place and it was fine.

Update via the comments:
"hmmmm.that's more of a rig than a fix.... next time, use a pencil erases on the back of the membrane and on the metal contact on the PCB, it will actually "fix" it instead of introducing foreign materials like tape that will only make it work temporarily and then probably melt and gum up your control board and make things worse."

Instrumental Innovators - Dave Smith: Synthesizer Pioneer - DVD


"Dave Smith founded Sequential Circuits in the mid-70s, and in 1977 he designed the Prohet-5 - the world's first microprocessor-based musical instrument and first completely programmable and polyphonic synth, which set the standard for all synth designs that have followed. In the last few years Dave has returned to the hardware instruments with the Evolver and Poly Evolver synths, which combine real analog electronics with digital processing to create yet another new world of unique instruments. This DVD includes a 90 minute complete history of Dave Smith from Prophet to MIDI to the PolyEvolver and roundtable discussion with Dave Smith, Roger Linn and Tom Oberheim."

BMH Audio & Elektronik Pro-One Processor Replacement

"We are working on a replacment processor for the 8021 in Sequential circuit's ProOne. It is a little pcb board with a modern sufacemounted processor. The board has pins that fits to the socket on the ProOne's pcb. So it's just to plug it in. The replacment board has even some more features built in:
* Midi input and output
* Two analog outputs, can be used to midi control for example filter cutoff etc.
* One analog input, have not decided what to use it for. Maybe to send midi data from pitchbend or modwhweel, or other analog signal"

Sequential Circuits Pro-One Modded

Title link takes you to shots via this auction.

"Regarding its insides, this Pro One is quite special in some ways:
- It has a Doepfer MCV-4 MIDI-CV interface built-in
- It has a modified Fatar CMK-37 Midikeyboard installed
As you can see on the pictures, the Pro One is in immaculate condition from the outside. While adding MIDI interface and MIDI Keyboard special care was taken to not modify the outside appeareance of the instrument. No extra holes have been drilled, all connectors utilize the existing jacks or holes. If necessary, all modifications can be reversed. From the outside this instrument looks like a perfect-shape stock Pro-One!

The modifications have been implemented with great care and make the Pro One quite powerful in a modern MIDI environment. With this Pro one you can:
- Play the synth via external MIDI-input
- Play the synth via velocity sensitive internal MIDI-Keyboard
- Use MIDI velocity to control Filter cutoff. There is a pot on the back to adjust modulation amount of Filter cutoff, so you still have the pot for Keyboard follow available independently - this is not possible on stock Pro-Ones
- Use MIDI aftertouch to control Frequency of second Oscillator. This is especially useful for sync sounds which the Pro One is famous for
- Use the internal MIDIkeyboard to record your performance on an external sequencer or use the Pro One as a small Masterkeyboard. I found it is a big difference if you play directly on a synth and record what you play or have to utilize a remote Masterkeyboard to play a synth via an external MIDI-CV converter.
- Forget also the trouble with J-wire keyboards, corroding contacts, uneven Keys and crappy feeling on usual Pro Ones. This keyboard lets you play the Pro one just like any other modern synth!

As a result of the modification the integrated Arpeggiator, Sequencer and CV in/out are not available anymore, I needed the ARP/SEQ switch to implement the Local on/off function and CV Jacks for the MIDI in/out. But since you have MIDI control anyways I believe there is no point of having these functions and connectors anymore.

The MIDI in and out jacks are utilized via using the existing CV jacks. A special cable is provided to convert from this jacks to standard MIDI connectors (see picture). All this has been done in order to leave the outside appearance of the instrument untouched.

Apart from that the unit has been calibrated to factory specs recently and works 100%."

Update via Stephen in the comments:
"- Nearly all tantalum caps, especially on the rails, were replaced with electrolytics
- power supply caps were replaced, regulators solder joints were resoldered and old thermal paste was removed and replaced with new paste. PS was calibrated
- analogue board was scaled, weak solder joints were retouched
- digital board DAC was adjusted, ROM upgraded, memory expansion installed, MIDI installed (MIDI jacks were installed in the sequencer interface holes
- control panel switches and pots were cleaned, replaced where needed. Solder joints on the pots were retouched or leads were fixed where needed.
- keyboard was complete disassembled, keys were washed in warm soap water. Crusty bushings were cut off, keyboard was cleaned, new bushings were installed. J-wires were aligned, resoldered where needed. Pitch and Mod wheels were adjusted
- Chassis/control panel, keyboard/mod wheel mountings were fitted to a synthwood.com black walnut case.
- new Prophet-5 and Sequential Circuits nameplates were installed.

I scrubbed this thing and I'd eat my dinner off of it."
