[linux-audio-user] ANN: bristol 0.9.5-89

[Nick Copeland]

Build 89 has been uploaded to sourceforge. It is likely to be unstable since 
quite large changes were made to the MIDI interface to support controller 
tracking in the GUI. The 2600 should now be finalised including the output 
bussing fixes and voltage manipulators. The sustain pedal should now work, 
lightly tested. MIDI controllers can be remapped internally, only interface 
is the text configuration file in $BRISTOL/memory/profiles/<synth>, you can 
edit this at your own risk.

Controller changes allow for MIDI surfaces to control the GUI, and hence the 
engine. Rather spuriously, to be able to modify and play the synth then both 
the GUI and engine need to be patched into the MIDI devices with whatever 
connection application you prefer - controller changes are tracked in the 
GUI and this causes the parameter changes to be sent to the engine.

Having this support immensely enhances tweaking the synths. You can map 
controllers by clicking the middle mouse button in a device and then moving 
the desired controller. You can select multiple devices to enable ganging of 
controls and the controller profile should be maintained. The mappings for 
each algorithm are saved when a patch is saved. They are only loaded on 
boot, but mappings should not be volatile. Reselecting a device with the 
same middle mouse button will remove the registration.

Pitch and Pan controllers should now be notched in the GUI, and a fine 
adjust is available with <Control><Button_1_Motion>.

The rotary shading was altered and a few other fixes were integrated. The 
transparent patch layer was optimised bya factor of 4 to 5 fold so loading 
the 2600 memories should be a lot faster.

Feedback on the controller mappings would be greatly appreciated, the 
interface is new and will probably give some problems. When the interface 
works then program change support will be integrated along with more GM2 
functionality.

Regards,

Nick.
