MTG Pro One CPU  
===============


Last Minute Notes
-----------------

 - If the Pro One does not reboot at the end of a Sys Ex firmware load, make
   sure your MIDIOX settings match the values in the (latest) PDF manual.

 - After you update your firmware you should perform a three finger reset-to-
   defaults operation (see manual). This will clear out the sequences and set
   the user parameters to a known state.

 - Note: The TTL MIDI signals on the module PCB are 3v signals (5v tolerant).

 * The REC switch remembers latched Arp data even if you turn the Arp off. You can
   go back to the Arp with these keys saved. However, you need to turn REC off 
   before you can play the keyboard again in normal mode or switch the sequencer
   on. This is by design. 

 * If your sequence or arpeggio does not start, it's probably because you have 
   the MIDI Clock enabled. Press PLAY on your attached drum machine or sequencer
   (or set the clock source back to LFO).

 * I am playing with the default (blank) sequences. You should write your own
   before using the sequencer.



Release Notes
-------------

Version 1.00
 - This offers the basic functionality I envisioned when starting this project. I will
   continue to add features and fix bugs.
 - Added loadind/saving sequences over MIDI.
 - Added sequence stop mode so that the seq stops on user switch anytime or only 
   end-of-seq. You can't switch to a blank sequence in the new mode (safety feature).

Version 0.18
 - Added arpeggiator Down mode option as an alternate to Up/Down.
 - Added live switching between Up and Up/Down (or Down) moded on arpeggio boundaries.
 - Added a MIDI pacing (delay) parameter (#08) for dealing with old synth MIDI issues.
 - LOTS of little bug fixes and I hope I didn't introduce any new ones!

Version 0.17
 - The MIDI clock table includes a setting (and it's the default one) that chooses
   the LFO/Ext clock instead. This is now the official way to choose the clock
   source. No more 1/4" plug required, but please leave the RPT/EXT switch off.
 - Added Sys Ex commands for altering the various settable parameters.

Version 0.16
 - Repaired a bug I introduced in v0.15 that disabled the external arp/seq-clock- 
   in -- *however* for the time being if you want to use MIDI clock you may need to 
   insert a 1/4" plug (with a 1k resistor across it) into the GATE/CLK IN to disable
   the LFO signal. I will come up with a more elegant strategy shortly.
 - Pro One CPU (not talking about the bootloader here) now responds to MIDI Universal
   Device Inquiry with a human readable version string. More Sys Ex to follow... 

Version 0.15 
 - Swapped the sense of the keys held down for setting the MIDI Channel.
 - Added MIDI Clock In for the sequencer and arpeggiator and added settable clock
   rates for it. Accidentally killed the ext-clk-in if using my sync-to-clk mode.

Version 0.14
 - Added functional MIDI-OUT note/on off. In the sequencer and arpeggiator the
   output is (obviously) monophonic, in normal keyboard mode the keyboard MIDI
   OUT is polyphonic.
 - MIDI note range changed to C2 through C6.
 - Added the TRIG pulse info to the default sequences since the default seq mode
   is Sequence Tie enabled.

Version 0.13
 - Modified sequence tie mode gate time to 100% from stock 50%.
 - Added functional MIDI-IN note on/off (last note priority).
 - Added power-on settable MIDI Channel.

Version 0.12 - Initial release
 - Added the power-on settable flash parameters.
 - Added MIDI Note on/off on ch 1 code for testing (only).
