PRO-2000 MULTI-CHANNEL MIDI TO CV CONVERTER Operating manual
INTRODUCTION Congratulations on your purchase of the Kenton Electronics PRO-2000 multi channel MIDI to CV converter, which has been designed to give you maximum flexibility, whilst maintaining ease of use. The converter has 10 completely independent sections - called channels A, B, C & D plus Aux’s 1 to 6. Each can be assigned its own MIDI channel, and controlled independently from the others.
such as Korg & Yamaha, (MS20, MS10, CS5). The Pro-2000 has been designed to handle these synths as well, it is simply a case of switching between the two systems in software. (See CV/Hz Select later) Some synths do not have CV, Gate or Filter inputs, such as the TB303. We can fit or supply socket kits for most monosynths that do not have inputs. Contact us for details. CHANNEL C, MIDI channel filter This is used to rechannelize or filter MIDI data.
FRONT PANEL Each channel, A and B, has LED indicators to indicate when that channel`s Gate is on. There are three more LED status indicators; One is marked DATA. This illuminates when the PRO-2000 is receiving MIDI data. The other two are marked PARAMETER and VALUE. These indicate which mode the PRO-2000 is in, and are toggled by the SELECT button. Four buttons; SELECT, ENTER and INC and DEC. - These are for editing the PRO-2000.
SETTING UP YOUR PRO-2000 MIDI CONNECTIONS MIDI IN - connect this to the MIDI Out of your MIDI synth or MIDI sequencer using standard MIDI cables. MIDI OUT - connect this to the MIDI In of your MIDI sequencer or old synthesizer. This is only needed if you will be editing the PRO-2000 using SYSEX or doing MIDI data dumps, or if you are using the MIDI channel filter. MIDI THRU - this provides a copy of the information coming into the MIDI In socket so that you can "daisy-chain" several MIDI devices.
THE ARP CLOCK & SYNC 24 OUTPUTS CLOCK PULSE - (arpeggio clock) - this output provides a 5 volt clock pulse related to the incoming MIDI clock. The ratio of MIDI clocks to arpeggio pulses can be adjusted - (see CLOCK PULSE DIVIDE). A +5 volt level will be output on the first MIDI clock after a MIDI start (or continue if selected) is received, and thereafter dependent upon the CLOCK PULSE DIVIDE ratio. You may for example connect this to an input marked Ext. Clock In on an analogue drum machine or sequencer.
PARAMETERS THE FOLLOWING PARAMETERS ARE THE SAME FOR BOTH OF THE CV CHANNELS, A, B (where x is the channel) CV x SYNTH CHANNEL x (1 to 16, defaults: A=1 B=2) - sets the MIDI receive channel for PRO-2000 analogue channel. CV x NOTE PRIORITY (low/high/newest, default: newest) - sets the note priority. If set to "Lowest" then the new note played takes precedence if it is lower than the preceding note. If set to "Highest" then the new note played takes precedence if it is higher than the preceding note.
CV x LFO DEPTH CONTROL (pb, vel, aft, controllers 0-119, default: #1 mod wheel). - assigns which MIDI controller will control the LFO depth of modulation of the CV output. CV x LFO DEPTH AMOUNT (for controller maximum 0-127, default:65). - allows you to set the maximum LFO depth for the CV out CV x LFO ASSIGN Use LFO number (1 to 2, default: A=1, B=2) - lets you assign which of the two inbuilt LFOs will modulate the CV outputs.
DIGITAL OUTPUT PARAMETERS ChC DATA FILTER MIDI Receive Channel (1 to 16, default: 3) - sets the MIDI receive channel for the MIDI channel filter. Only MIDI data on this channel will be retransmitted to the PRO-2000 MIDI out. It can be retransmitted on a different channel if necessary; see below. ChC DATA FILTER MIDI Transmit Channel (1 to 16, default: 1) - sets the channel that the MIDI data from the MIDI channel filter is retransmitted on.
AUXILIARY OUTPUTS THE FOLLOWING PARAMETERS ARE THE SAME FOR EACH AUXILIARY 1 TO 6 (where x is the auxiliary number) AUX x AUX OUTPUT x Receive channel(1to16, default: 1 to 6 set to 1 to 6 respectively) - assigns the auxialiary to which ever MIDI channel you wish to set it to, i.e. to get the auxiliary to respond the synth on CV channel A, set it to the same receive channel as that synth.
Pitchbend range is set globally for all any auxes in CV mode using the Ax1-6 Pitchbend Range parameter.
Gate from Notes - this allows the selected auxiliary output to give a voltage output in response to notes on any MIDI channel you select - the off and on levels can be changed by using the Min & Max (and Reset) level controls - Min sets the voltage when the gate is off and Max sets the level when the gate is on. For example if you set min to zero and Max to 25 you will have a 5v gate signal or if you set Min to 25 and Max to zero you will have an S-trig with +5v pullup.
LFO x WAVESHAPE # (1 to 9 as below, default: triangle[1]) - sets the wave shape for the LFO 1, Triangle 2, Sawtooth up 3, Sawtooth down 4, Square 5, PulseWidth 10% 6, PulseWidth 20% 7,1 PulseWidth 30% 8, PulseWidth 40% 9, Sample + Hold (random depth) LFO x MIDI SYNC (off, 1 to 96, default: off) - allows the LFO waveform to be synchronised to MIDI clock, with a variable divide ratio.
Below is a table of values you can set the divide ratio to to obtain a clock pulse at various musical time intervals: 13
Note type; Crotchets Crotchet triplets Quavers Quaver triplets Semiquavers Semiquaver triplets Demisemiquavers Demisemiquaver triplets Divide ratio; 24 16 12 8 6 4 3 2 CPQN 1 2 3 4 6 8 12 SYNC CLOCK Polarity: +ve/-ve clock pulse (default: +ve) - sets the type of clock pulse sent from the clock pulse output.
MIDI Diagnostics Mode The Pro-2000 has a built-in MIDI analyser function. This feature allows you to see what types of MIDI messages are being transmitted by your master keyboard/sequencer, making the PRO 2000 a useful diagnostic tool, which can help you when you have a problem with your MIDI set-up. To enter analyser mode, you must power on the PRO 2000 whilst holding the SELECT button. The display will then show ‘CHANnel’, ‘NOTE#’ and ‘VELOCity’, and will display the relevant data, below the heading.
PRO-2000 SYSEX INFORMATION The first five bytes of sysex for the PRO-2000 are always the same for all data types [ [ [ [ [ 1] 2] 3] 4] 5] 0F0h 00h 20h 13h 02h - Sysex command - Company ident first byte - Company ident second byte - Company ident third byte - Product code [ 6 ] 0ddd0000 - where ddd is data type if ddd = 100 = memory dump if ddd = 010 = data change if ddd = 001 = dump request (40h) (20h) (10h) ------------------------------------------------------------------ddd = 001 = dump request [ 7
specified memory location and also to the edit buffer (current setup) the data will be immediately utilised and the display will be updated. You may change the block number of a memory dump without causing any problem. For example, data that came from memory 6 could be returned to the current setup by merely changing the 06 in byte [ 7 ] to a 00. Parameter data are stored in the following addresses.
