  • Page 23: Parts

    MD900 PARTs The MD900 is equipped with 4 parts, i.e. it can generate four different sounds simultaneously. The up to 16 voices for these sounds are divided. The advantage is that the polyphony can be distributed to the sounds where it is needed. In other words there are 4 synthesizers (defined as PARTs) that share a common voice pool.

    (looped MIDI files per clip) or the "drum grid pattern" is possible in an impressive way. These features make the MD900 a "groove box". The Arranger in the MD900 allows you to save the entire setting that is: Presets, drum kits, samples, clips, sequencer/arpeggiator settings and arrangement specific MIDI settings.
  • Page 25: Midi Settings

    MD900 MIDI settings MIDI Devices If you want to use a connected USB-MIDI Keyboard you have to map the USB device to a MIDI Port (P1-P4). This will then allow us to assign it to a part (A-D). In the default settings the DIN MIDI In is mapped to P1 . To assign our connected USB- MIDI Device we go to the tab MIDI->Devices see Figure 7.
  • Page 26: Midi Inputs

    MD900 MIDI Inputs Now we can use the MIDI inputs and thus set them. To do this, we switch to the corresponding tab IN-A,B,C,D In this panel we can set the MIDI inputs (Port & Channel) among others. The LABEL: PORT-CHN allows the selection of the port (e.g. P2). Pressing the encoder key Figure 8.
