SYNTHS
The MIDI 1U System supports multiple MIDI Channels through the concept of
synths
. In MIDI 1U
lingo, a “synth” defines the device you wish to control, and the MIDI channel on which you want to
control it.
Intellijel’s MIDI 1U system can control up to 10 different synths on up to 10 different MIDI channels.
By itself, without any CVx expanders, the MIDI 1U can control up to two monophonic synths (called
synth 1
and
synth 2
) on up to two different, user-selectable MIDI channels. Adding one or more
CVx expander modules increases the available synth count (and MIDI channel count) to 10, with
synth 3 - synth 10
capable of monophonic, polyphonic, or drum operation.
Specifically:
● Monophonic
Monophonic synths are configured to control a single oscillator or monosynth voice. This is the
usual operation of most monophonic Eurorack devices, and the only mode supported by an
unexpanded MIDI 1U.
Various related parameters, such as MIDI channel, pitch range, note priority mode, pitch bend
range, coarse tuning, and trigger length can be set for each monophonic synth.
● Polyphonic
Polyphonic synths are configured to control a polyphonic oscillator or synth voice. This option
requires a CVx expander, and is available only for Synths 3-10.
Polyphonic synths support a maximum of 8 voices, with the actual number of voices determined
by how many outputs you assign to a particular synth. For example, if you use the
Intellijel
Config
app to configure a CVx to have 4 pitch outputs and 4 gate outputs assigned to the same
synth, then you will have 4-voice polyphony. If you assign 8 pitch outputs and 8 gate outputs to
the same synth across multiple CVx modules, you will have 8 voice polyphony, etc.
Various related parameters, such as MIDI channel, pitch range, voice allocation, pitch bend
range, coats tuning, and trigger length can be set for each polyphonic synth.
● Drum
Select this option to control a drum/percussion voice or sampler module, where different MIDI
note numbers trigger different drum sounds. This option requires a CVx expander, and is
available only for Synths 3-10.
Drum mode supports up to 8 voices per MIDI Channel. Use the
Intellijel Config
app to assign
voices to MIDI Note numbers and determine whether the output is a gate, trigger or velocity
value. If multiple outputs are assigned to the same MIDI Note, those outputs use only a single
voice.
