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%."
i like the fact that no extra holes were drilled and the proone can be put back to original. that take foresight and maintains the collectible value of the synth while making it a more contemporary instrument. its the right way to do it.
ReplyDeleteMeh. I'd rather have an un-modded Pro-One with the Pratt-Reed keyboard with new bushings and still be able to use the arpeggiator and sequencer.
ReplyDeletenot having the arp and sequencer is a big loss. all the mods are not worth the sacrifice.
