Persist more Dexed parameters in per-instance state

[probonopd]

Trying to recreate TX816-style performances by combining multiple Dexed instances in the DAW, I am running into the issue that some of these parameters seemingly are only persisted across all instances of Dexed (in C:\Users\%USERNAME%\AppData\Roaming\DigitalSuburban\Dexed\Dexed.xml), whereas the TX816 requires some of these parameters to be different across the 8 tone generators:

  <VALUE name="normalizeDxVelocity" val="0"/>
  <VALUE name="pitchRange" val="0"/>
  <VALUE name="pitchRangeUp" val="0"/>
  <VALUE name="pitchRangeDn" val="1"/>
  <VALUE name="pitchStep" val="0"/>
  <VALUE name="sysexIn" val=""/>
  <VALUE name="sysexOut" val=""/>
  <VALUE name="sysexChl" val="0"/>
  <VALUE name="showKeyboard" val="1"/>
  <VALUE name="wheelMod" val="0 0 0 0"/>
  <VALUE name="footMod" val="0 0 0 0"/>
  <VALUE name="breathMod" val="0 0 0 0"/>
  <VALUE name="aftertouchMod" val="0 0 0 0"/>
  <VALUE name="engineType" val="1"/>
  <VALUE name="dpiScaleFactor" val="1.0"/>

Specifically:

• pitchRangeUp
• pitchRangeDn
• pitchStep
• wheelMod (is already persisted per instance via PluginData.cpp)
• footMod (is already persisted per instance via PluginData.cpp)
• breathMod (is already persisted per instance via PluginData.cpp)
• aftertouchMod (is already persisted per instance via PluginData.cpp)

Likely the missing ones would need to be added to DexedAudioProcessor::getStateInformation() before

dexed/Source/PluginData.cpp

Line 331 in b6cf2e9

dexedState.setAttribute("engineType", (int) engineType);

for saving the per-instance state,

and to DexedAudioProcessor::setStateInformation()

dexed/Source/PluginData.cpp

Line 411 in b6cf2e9

setEngineType(root->getIntAttribute("engineType", 1));

for applying the per-instance state.

My attempt at implementing this: probonopd#1

Running into

dexed/Source/PluginData.cpp:332:57: error: ‘class Controllers’ has no member named ‘pitchRangeUp’

Apparently https://github.com/asb2m10/dexed/blob/master/Source/msfa/controllers.h needs to be changed but I don't know how.

Any help appreciated.

The DX7II ACED (per-voice additional parameters) format (documented on page "Add-9" of the DX7II manual) contains, among other similar parameters, pbr = 2 # 0 .. 12 # Pitch bend range. So these things should clearly be possible to persist per voice if we want to have DX7II like configurability.

(It appears that some parameters defined in ACED cannot be configured in Dexed so far at all, though - which is partly covered by #165.)
