#85 Emulator pitchbend off by 1 semitone

[Anonymous]

Some of the emulator's default pitch bend is set to 1 semitone, instead of the default two.

2 semitone pitch bend:
Mini Moog
Arp Axxe

1 semitone pitch bend:
Polysix
Pro-52

Might be a fairly simple one line fix, but I don't know how the poly and pro related to each other code-wise.

Need to check this. The default should indeed have been 2 semitones. The value is configurable but +/-1 is not supposed to be the default.

Did not receive a notification of this bug, apologies for the late response.

So the problem is cause by a mismatch the emulator names. The code attempts to find the emulator by comparing the diverse parameters with the known names: the -pro52 will start a Prophet-52 emulator however it will only get the emulator default if it is started with the option -prophet52 (not -pro52). The 'polysix' actually needs to use a parameter called -poly to get the emulator to work, that is for historic reasons.

I can work on fixing some/all of them so that -poly/-poly6/-polysix work correctly, -prophet52/-pro52 also. I would have to review the other exceptions and thenenforce another default anyway.

You can get the internal emulator names from 'startBristol -summary', note that this same issue will also affect things like detuning, voicecounts and other parameters.

This is going into pending, the next release will take a defaultt 2 semitone pitchwheel depth (inherrited from the default emulator, the B3), and the code will also recognise the aliases.

Will be in 0.60.8
