New Parameter Reference
The Tauntek MCU replacement mod adds many new features and parameters, note that not all are controllable by Midi CC. Here are the new editable parameter descriptions by R. Grieb. For additonal information about new features and behaviors, visit Tauntek's webpage linked in the sidebar.
Parameter 65: LFO1 Waveform [CC#90]
selects the waveform for LFO1. This LFO is used for modulating the DCO frequencies and also the VCF cutoff. This setting is saved in the patch.
Waveform choices are:
0: Triangle
1: Ramp Up
2: Ramp Down
3: Square
4: Random
Parameter 66: LFO2 Frequency [CC#14]
controls the frequency of LFO2. This LFO is only used for pulse width modulation. This setting is saved in the patch.
Parameter 67: LFO2 Waveform [CC#15]
selects the waveform for LFO2. This setting is saved in the patch.
Waveform choices are:
0: Triangle
1: Ramp Up
2: Ramp Down
3: Square
Parameter 68: Vibrato Source [CC#81]
selects LFO2 as the modulation source for the DCO frequency. This setting is saved in the patch.
Parameter 68 = 1:
LFO1 mods DCO freq, can be delayed
LFO1 mods VCF cutoff, can be delayed
LFO2 mods Pulse width, mod starts immediately
Parameter 68 = 2:
LFO2 mods DCO freq, can be delayed (with LFO1 delay setting)
LFO1 mods VCF cutoff, can be delayed
LFO2 mods Pulse width, mod starts immediately
Parameter 71: Random Arpeggiator Enable [NO CC#]
Enables random arpeggiator mode. In this mode, the arpeggiated notes are played in random order. The up/dn and range select switches also affect note selection.
This setting is not saved in the patch, and is set to "off" (0) at power up.
Parameter 72: Program Increment Behavior [NO CC#]
The Poly61 always uses the Up and Down switches to adjust the currently displayed
parameter, even if Program is selected. New parameter 72 enables changing this behavior.
If parameter 72 has a value of 1, when the Program LED is lit, the up and down switches
can be used to step through the patches. This is similar to the pedal input except
you can increase or decrease the patch number. If parameter 72 has a value of 0, the
up and down switches only affect the displayed parameter, as in the original firmware.
The parameter 72 value is saved in EEPROM when power is off
Parameter 73: Key Assignment Mode [CC#80]
selects either normal rotate assignment of keys to voices, or "always start with voice 1" mode. In the new mode, whenever no key is pressed, voice assignment is reset to start with voice 1 on the next key press.
This parameter is set to rotate mode (0) at power up.
Parameter 81: MIDI Channel [NO CC#]
used to set the MIDI channel. It is saved in EEPROM when power is off. MIDI out Note messages are sent on MIDI channel + 1.
Parameter 82: MIDI Output Mode [NO CC#]
selects the MIDI out mode. It is set to 0 at power up.
0: All keys pressed are played, and also send Note On and Note off
1: Any keys pressed when all voices are already used will send Note On. Note Off message is sent for released keys that are not assigned to a voice. This could be used to chain two Poly61's. The one that is receiving the overflow should be in Mode 0 so that it plays all notes received.
2: This mode was inspired by the "alternating rotate" mode of the Oberheim Matrix 1000. As keys are pressed, they alternate between being assigned to a voice and being sent out on MIDI. Note Off message is sent for released keys that are not assigned to a voice. This could be used to chain two Poly61's. The one that is receiving the overflow should be in Mode 0 so that it plays all notes received.
Parameter 83: MIDI Program Change Enable [NO CC#]
enables (1) or disables (0) sending MIDI program change messages when a new program is selected. This setting is saved in EEPROM when power is off.
Parameter 84: Arpeggiator Clocking Mode [NO CC#]
selects the arpeggiator clocking mode as follows:
0: Internal clocking mode
1: MIDI clocking, 48 clocks/step, no Start/Stop required
2: MIDI clocking, 24 clocks/step, no Start/Stop required
3: MIDI clocking, 12 clocks/step, no Start/Stop required
4: MIDI clocking, 48 clocks/step, Start/Stop required
5: MIDI clocking, 24 clocks/step, Start/Stop required
6: MIDI clocking, 12 clocks/step, Start/Stop required
7: MIDI clocking, 6 clocks/step, Start/Stop required
