From Steven.Collins@cs.tcd.ie Tue Aug 2 23:54:22 1994 Date: Tue, 02 Aug 1994 15:05:38 +0100 From: Steven Collins To: analogue@magnus.acs.ohio-state.edu Subject: Kenton Pro-4 specs. Ok y'all, here's the spec sheet that I received from Kenton about 3 months ago. INTRODUCTION The Kenton Electronics Pro-4 CV converter is effectively four completely independent CV converters, each of which can be given its own MIDI channel. If takes the MIDI signal from a MIDI sequencer or mother keyboard and turns this into the voltage required to control most monophonic analogue synthesisers. The Pro-4 will output the standard 1 volt per octave CV and +15 volt gate signals required to control the pitch and duration of the notes, plus there are 8 auxilliary outputs, each of which can be assigned to any of the four synth channels. To give you even more control over your synth the Pro-4 has four completely independent LFOs each of which can be used to modulate any or all of the CV voltages and can even be used to modulate four of the auxilliary outputs. The LFOs can each be controlled by MIDI, allowing you to change the frequency waveform and modulation depth, and sync to MIDI clock. The Pro-4 even has built in glide/portamento which is also under MIDI control. The Pro-4 lets you adjust transpose and pitchbend ranges simply from the front panel and trimmer adjustments are also provided to let you tune the Pro-4 to exactly match your synthesiser. The Pro-4 comes with trig/s-trig outputs as standard to cope with the widest possibile variety of synths. For synths. that use the Hz/V system (instead of 1 colt/octave) and optional 4 channel Hz/V unit is available that fits inside the Pro-4 and provides Hz/V outputs in addition to the standard CV outputs. The Pro-4 has several additional synchronisation and control outputs for ease of connection to a variety of other synths and drum machines. (see below) The Pro-4 is a solidly built, high quality and completely self-contained 1U high rack unit with internal power supply available in a vairety of voltages. The front panel has 4 push buttons, a data entry knob, and a 2 line by 20 character backlit LCD display for ease of setup and editing. You can create several setups and save them in non-volatile memory or dump them to disk via sysex. ======== 4 INDEPENDENT CV OUTPUTS...A,B,C,D - each independent CV channel boasts the following features: * Assignable MIDI channel (1-16) * Built in portamento/glide functions * Modulation amount variable by any MIDI controller * Optional Hz/Volt output in addition to normal CV output * Assignable note priority (HI, LO or NEW) * Modulation from inbuilt LFOs (1-4) * Configurable TRIGGER or S-TRIG outputs * Polyphonic mode for use with OB-4 etc. ======== 8 AUXILLIARY OUTPUTS.....1-8 Assignable to any MIDI controller on any channel A,B,C,D,E,F,G or H Further control of your synth is made possible using the Auxilliary outputs 1-8. These can be connected to extra inputs such as VCF or VCA provided on some synthesisers giving you full MIDI control over Filter and Volume for example. In addition, Auxilliary outputs 1-4 can be modulated by any of the internal LFOs (1-4). The amount oof modulation can be controlled by any MIDI controller. ======== 5 DIGITAL OUTPUTS.... Five special outputs are available to interface directly to some of the early digitally-controlled synths and drum machines to provide MIDI control capabilities. * DIN SYNC 24 output to synchronise early Roland equipment to MIDI Clock/Stop/Start. * MIDI OUT socket with MIDI filtering capabilities to channelise an early 'omni-on' synth. * Kenton auxilliary Digital Interface for future expansion (control of TR-606 or TR-808 drum notes). * Optional DCB port for polyphonic control of Roland Jupiter 8 & Juno 6/60 synthesisers. * Optional WASP port for controlling EDP Wasp synth. [KADI, DCB and WASP ports each have their own independent MIDI channels] ======== CHANNEL USE ON THE PRO-4 (these are analogue or digital output channels and shouldn't be confused with MIDI channels) A,B,C,D are CV/GATE/TRIG channels (standard) E is a 9 pin digital output intended for the EDP WASP (option) F is a filtered MIDI output (standard) G is a DCB port for some early Roland equipment (option) H is a 15 pin digital output intended for Roland 606/808 (standard) ======== Kenton PRO-4 is due for release in early 1994. Specifications are subject to change without notice. Price is expected to be 340.00 (UK Sterling) plus VAT (399.50 incl. VAT). Prices for the options are expected to be around 50.00 plus VAT for the add-on 4 channel Hz/Volt unit, 35.00 plus VAT for the Wasp Port, and 35.00 plus VAT for the DCB port. (the latter 2 include cables) ======== The Pro-4 (or indeed any MIDI to CV converter) is not generally the appropriate solution for the control of Polyphonic synths. Although a few early polysynths do have CV & GATE inputs fitted, this only enables you to use one of the voices, so you effectively get a monophonic synth when using CV & GATE. The way to control polysynths using MIDI is to get an internal retrofit, which of course KENTON can supply and fit for you. ======== Kenton Electronics Rear of 137-165 Hook Road, Surbiton, Surrey KT6 5AR Tel: 081-974-2475 - Fax: 081-974-2485 Errors and omissions excepted.

I've only worked with a Pro-2 and that was like heaven compared to the Doepfer MCV-1 but this is what the Pro-4's spec sheet says: - 4 independet CV-Outs each one with: - variable channel (1-16) - built in Portamento/Glide function - selectable note-priority (lo, hi, New) - 4 freely assignable LFO - modulation depth can be controlled with any Midi-controller - Trig + S-Trig outs - optional Hz/V output - polyphonic mode for OB-4 etc. - 8 Aux outputs, asignable to any Midi controller on any of the 4 channels - 5 digital outs - Din Sync 24 - Midi-Out - Kenton Aux digital interface for future extensions - DCB - WASP port for EDP Wasp.

LFOs (midi clock syncable) also modulate the pitch voltage, "modulation" (you choose the CController) will affect the depth of that modulation. So this adds an LFO to your synth ! The LFO could also go out one of the auxes for modulating something else besides pitch (overall fuckupedness etc.) It could modulate a controller that is being converted to voltage out one of the aux outs and used to control filter depth. The gate voltages can be assigned to talk arp (+13v ?). After attaching battery after battery to my gross Paia MV8 to boost the voltage up there.....

The DCB port (I don't have a DCB synth, btw) can be on a seperate MIDI channel. The Pro-4 has programable portamento of it's own, plus it can do regular pitch bends via any MIDI controller. It is all in how you set up your MIDI software. I have my Cubase system, for example, set to send additional LFO (internal to the Pro-4) to the various CV ins of my SH-101. When I send pressure (aftertouch) it kicks in the modulation whose speed is controlled by a slider on my PC-88. I'm pretty much still a MIDI novice and I hadd no trouble setting it up :) The Pro-4 is, imho, *very* user friendly :) PEACE OUT :) MARK
