The Mixer

The preenfm3 has a mixer section that allows you to define diferent features of each of the 6 instruments that are not available in the editor because not part of the sound itself.

Here is the first mixer page, the one that is shown up when you switch on your preenfm3.
Beside MIX at the top, you can see the name of the current mixer file. You can modify it when you save the current mixer.

Saving the mixer saves the 6 instruments at the same time as the mixer parameters.
In each of the mixer pages, the 6 encoders modify the value for one instrument from 1 to 6 corresponding to the number of the encoder you turn.


Mixer volume

On this page, as you can guess, you can modify the volume of each instruments. (Then PAN will be added soon).


Change the number of voices.

Mixe Voices

Modifying this can have an impact on the "Voice" and "portamento" parameter available in the editor.
If you set 1 here, "voice" must be set to "Mono" in the editor.
If you set 2 or more, "voice" must be set to "Poly" in the editor.
The idea is that Mono/Poly is part of the preset, while the number of not.


Instrument audio output.

Mixer Out

You can chose here on what audio output the instrument sound will be routed.
Single digit values will convert the instrument to mono.


Mixer Midi 1 | Mixer Midi 2 | Mixer Midi

You can specify here how each instrument will respond to midi channel input.
It's possible to have several (or even all) instruments responding to the same midi channel.
From here you can also filter out some midi notes if you want an instrument to respond only to a specific note interval.
On the screenshot instrument 5 responds to note 0 to 63 on channel 5, instrument 6 to note 64 to 127 on same channel.
The midi note shift has been used to make the instrument 5 play higher and instrument 6 lower. So that they sounds good even if the respond ton lower et higher midi note.


Preenfm3 instruments are not limited to occidental diatonique scale.
You can put any scala scale files on the SD card and use a different scale for each instrument.

Mixer Scala 1 | Mixer Scala 2 | Mixer Scala

For each instrument, you can specify it it must use a dedicated scala scale : Scala enable on the first page. You'll be able to set "on" only if you have scala scale files on your SD card.
The page 2 allows you to specify the scale for each instruments.
On the page 2 you have two choices to distribute the notes on your keyboard. Using Keyb will wait for a "C" to start a scale. Using cont (continuous) will start the following scale on the note following the previous one.
Chose what scale to apply for the instruments on page 3.


You can specify here some parameter that will be saved with you mixer session.

Mixer Scala 1

Global midi : is a channel number is specified here, all instrument will respond to it. It's follows the MPE midi recomandations.

Current midi : is a channel number is specified here, the current instrument (the one with a yellow number in the mixer, or the one you edit in the ditor) will respond to it.

Midi thru : do you want all midi in data to be copy (super low latency) on the midi out DIN5 jack.

Tuning : 440.0Hz is the default for the middle A, but might want to use a different frequency.
