Overview

This module converts a CV data stream into MIDI Pitch Bend messages.

MIDI Pitch Bend messages are defined over a generic range that is roughly -4000 to +4000. It is up to the synthesizer to determine how those values are mapped to musically useful changes, usually by setting a parameter with a name like "Bend Amount", which is specified in semitones. By matching the Range parameter of this module to the "Bend Amount" parameter on your MIDI Synthesizer, you can use this module to generate all sorts of interesting pitch effects.

Parameters

Base Value
Sets the Bend value generated when the CV input value is 0.0.

CV Scale
Scales incoming CV values by the value set here.

Range
Sets the expected bend range of the target synthesizer. In order to generate accurate bend ranges, set this parameter and the "Bend Amount" parameter of your synthesizer to the same value.

AutoScale
Determines whether incoming CV values are scaled to match the expected bend range. When on, incoming CV values are assumed to range from -1.0 to +1.0, and will be scaled to the semitone range specified by the Range parameter.

MIDI Channel
MIDI output channel to use for generated Pitch Bend messages.

(Data) Rate
This sets the maximum rate at which CC messages will be sent. The rates are:

• I (very high) -- no limit.
• H (high) 50 Hz -- every 20 ms.
• M (medium) 20 Hz -- every 50 ms.
• L (low) 10 Hz -- every 100 ms.

When generating Pitch Bend messages to MIDI hardware ports, be sure to use the "L" or "M" ranges, depending on how many other MIDI messages are being sent to the same port. The MIDI transmission rate (over physical cables) is 31.25 Kbaud, which comes out to about 1000 MIDI CC, Pitch Bend or Note messages per second. If you are only sending MIDI messages to modules or software running on the same computer, high data rates should not be an issue.

Ports

MIDI Pitch Bend messages will be generated based on values coming into the module through this port.

All MIDI Pitch Bend messages generated by the module are outputted through this port.
