Velocity Control
Marion Systems
The TVS-PRO keyboard sends the following MIDI OUT data:
• Note ON
• Note OFF
• Pitchbend
• Mod Wheel
• MIDI Clock
• MIDI Clock Start
• MIDI Clock Stop
MIDI Channel assignments when using TVS-PRO keyboard:
• UNISON - Output is on basic channel and basic c 1
• SPLIT - Low section of the keyboard is on the basic channel. High section is on basic c1.
• DUOPHONIC - Output is on the basic channel.
MIDI OUT from the Mini-Sequencer:
• Control information going to SEM A is output on the basic channel.
• Control information going to SEM B is output on the basic c1.
Sequencer transposition by keyboard:
• Sequencer transposition by the TVS-PRO keyboard is output on the basic channel.
Velocity Control
Keyboard Velocity can control the VCA loudness and the VCF frequency modulation. This is accomplished by
using the VCA switch for velocity-controlled loudness and the VCF Modulation controls for velocity-controlled
VCF sweeps.
Modulation Settings:
• When the VCA switch is positioned to the left, ENV1 directly modulates the VCA.
• When the switch is in the ON/EXT position, the amount of ENV1 that modulates the VCA is controlled
by velocity summed with aftertouch.
• Likewise, when the VCF modulation switch is set to ENV2, that envelope directly modulates the VCF.
• When the switch is in the EXT position, the amount of ENV2 that modulates the VCF is controlled by
velocity summed with aftertouch.
