Velocity Converter

MIDI Solutions Velocity Converter

The MIDI Solutions Velocity Converter applies selected velocity curves to incoming MIDI notes. Curves can be selected from 40 preset curves or a user defined curve. Even though the 40 presets offer a wide range of curves that are enough to cover most needs, the user curve makes the Velocity Converter a completely versatile device by allowing one curve to be created to an exact specification.

The Velocity Converter can apply a separate curve to each MIDI channel, allowing the velocity response of a sending keyboard to be matched to individual sound modules that are each set to receive on a different MIDI channel.

Another feature of the Velocity Converter is the option to assign velocities based on a selected incoming Control Change value. In this mode, the Velocity Converter monitors the value of a selected Control Change message on a selected MIDI channel, and applies this value to all incoming velocities on that MIDI channel. It is also possible to add an offset to this value to keep the outgoing velocities above a specified level.

The Velocity Converter is programmed by sending it MIDI System Exclusive messages. This can be done easily with the Processors Programming Tools software. Once programmed, its settings are retained even after power is removed. The Velocity Converter can be reprogrammed with new settings as often as needed.

The Velocity Converter is MIDI-powered, and requires no batteries or power supply to operate with most MIDI products. A MIDI indicator LED lights up when the product is powered and flashes when MIDI data passes through it.

Application Examples:

The main function of the Velocity Converter is to expand the velocity range of keyboards that are unable to send the full velocity range, like the older Yamaha DX7, however it can also be used to match the velocity sensitivity of a keyboard to a number of different sound modules. For example, let's say you are using a single keyboard to play two different sound modules, each receiving on a separate MIDI channel. If one of these sound modules is very sensitive to the slightest touch, while the other barely responds unless the keys are hit really hard, the MIDI Solutions Velocity Converter can be used to apply a separate velocity curve to each MIDI channel, so you can match the velocity response of your keyboard to each sound module in your setup, correcting for these differences.

The Velocity Converter also includes a function that can be used to apply continuous controller data to MIDI velocities. For example, if you play a wind controller that sends constant velocity values for each note played, then each note will produce a sound with identical attack, making for a sound that is boring and uninteresting. The Velocity Converter can actually apply the value of an incoming controller (with an offset, if necessary) to the velocity values, allowing you to add this inherent expressiveness to the sound to give it more depth.
