Korg Z1 & SoundDiver - Oscillator Switches

[Z1Muso]

I've recently started using my Korg Z1 once again with SoundDiver but have noticed there appears to be no way to switch the Oscillators on/off using the software. The only way I can see is to manually switch them on/off via the hardware and then store the status.

In the Midi implementation for the Z1 have found the following table:

[*2]:MixerSW
+-----------+---------------------------+
| vv | Description |
+-----------+---------------------------+
| 0--- x--- | OSC1 SW |
| 0--x ---- | OSC2 SW |
| 0-x- ---- | Sub OSC SW |
| 0x-- ---- | Noise Generator SW |
+-----------+---------------------------+

by using SendSX found the following:

F0 42 30 46 41 01 7E 01 00 00 F7 : turns Osc 1 switch off
F0 42 30 46 41 01 7E 01 01 00 F7 : turns Osc 1 switch on
F0 42 30 46 41 01 7F 01 00 00 F7 : turns Osc 2 switch off
F0 42 30 46 41 01 7F 01 01 00 F7 : turns Osc 2 switch on
F0 42 30 46 41 01 00 02 00 00 F7 : turns Sub Osc Switch Off
F0 42 30 46 41 01 00 02 01 00 F7 : turns Sub Osc Switch On
F0 42 30 46 41 01 01 02 00 00 F7 : turns Noise Osc Switch Off
F0 42 30 46 41 01 01 02 01 00 F7 : turns Noise Osc Switch On

As there seems an easy way to turn the Oscillators on/off have the SoundDiver programmers missed out on something crucial?
