How to Turn Effects On and Off via MIDI

Changing Effects via MIDI

Here's a perfectly reasonable approach to setting effects from your computer sequencer, but this will NOT work:
1. In Sequencer Mode, set all the effects the way you want them.
2. From your computer sequencer, send the 01 a Dump All Sequence command.
3. The 01 sends all its sequencer data, which the computer sequencer stores in a SysEx file.
4. When it's time to play the song, the computer sequencer first sends all the Track settings that are stored in the computer's sequence (what you see on the computer screen).
5. When the song actually starts, the first MIDI thing sent is the SysEx file, which includes the effects settings
6 And the song sounds all wrong.

You'll find the SysEx file had the effects settings all right, but all the Track settings (Program, Pan, Volume) were at their power-on values (Prog=A00, Pan=5:5, Volume=127). When you issued the Dump All Sequence, these default values were stored along with your effects settings. Although the computer set all the tracks up correctly before playing the song, the SysEx overwrote all those settings with default values.

"No problem," you say. "I'll have the computer play the beginning of the sequence, which will set all the Track parameters. Then I'll do the Dump All Sequence, and everything will be saved." Or so you'd think. Wrong!

If you set things like Program, Volume, and Pan from the 01 panel buttons, the settings can be dumped (output) to your computer sequencer, and the sequencer will capture the data. If those same settings were made by your sequencer (not using the 01 panel buttons), those settings can NOT be dumped (output) to your computer sequencer. Again,

Sequencer info received into the 01 by SysEx dump will not be output in a SysEx dump!

Solution #1: Set the 01's effects, Dump All Sequence, and save the SysEx file. In your computer sequencer, set up the song to (re-)send all Track parameters AFTER the SysEx is sent. This means you have to send a Patch Change, Volume, and Pan MIDI message for every track you use. Although tedious, this is probably the best approach because all your song settings are easily visible and in one place (try looking at a SysEx file sometime).

Solution #2: Hand-enter Track parameters into the 01, then Dump All Sequence. If you don't plan on changing track assignments or settings, this solution will get you by.

What follows is how I use Cakewalk 3.0 to change the 01's effects settings.
(Note: There is a bug in newer versions of Cakewalk and they will not work in my system. Cakewalk tech support has refused to help, so I cannot recommend or endorse any Cakewalk products.)

BANK
The MIDI Bank Change message is sent as a Continuous Controller message on the Global Channel. The message has three parts: Bank Change MSB (Most Significant Byte), Bank Change LSB (Least Significant Byte), and then a Program Change message.

For example, when you first turn power on, you are in Bank A.
If you push BANK to change to Bank B, the 01 sends:
Controller Change/Bank: 00,
Controller Change/Bank: 01,
Program Change 00.

Push BANK again,the 01 sends:
Controller Change/Bank: 00,
Controller Change/Bank: 00,
Program Change 00.

Notice the LSB of Controller 0 is 0 for Bank A and 01 for Bank B. Also notice you can’t just change Banks without specifying the Program (or Combi) number in the new Bank.

Pressing  BANK, UP-ARROW, or DOWN-ARROW sends PROGRAM CHANGE (192)

DISK

2. GLOBAL P0:GLOBAL has a MIDI Filter parameter called EXCLusive that defaults to DISabled. When disabled, you have to go to GLOBAL P8:DATA DUMP to send or receive MIDI data. By ENAbeling EXCL, SysEx data can be sent and received while in SEQuencer mode/screens.
