MD900 TOUCH-display overview The following Figure 5. [Touch-Display] shows the general controls. Continuous controller groups 1-4 allow setting parameters of a corresponding section (e.g. Oscillator 1). Each continuous controller group can have up to 5 levels. I.e. the corresponding parameter of the group can be selected on the touch display and then be changed by means of the endless controller.

MD900 INSTRUMENTS The independent drum instruments are one-shot sample players. To clarify the relationships, let's have a look on the file structure: For the Instruments see Figure 10 [DRUM-SAMPLE STRUCTURE]. This shows the relationship to the file structure. Each instrument has its access location to its samples which are offered for selection (Samples selection list).
MD900 Sidechain This parameter allows mixing these instruments to the sidechain Info: The DRUM sample player is quasi the 5th bus. This bus can be processed in the effect section. (e.g. PART and can play 14 samples simultaneously. It Dynamic Compressor)
MD900 PARTs The MD900 is equipped with 4 parts, so it can produce four different sounds simultaneously. The up to 16 stereo 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 (we call them PARTs) which share a common voice pool.
MD900 If a category is now selected in the "List View", the presets are SYNTH A (B, C, D) listed and can now be selected and loaded in the same way. See Preset-Selection Figure 14. [Presets] This colored main menu tab represents the synthesizer of the corresponding PART.

The last opened pattern can always be mode.
MD900 The STEPS parameter defines the number of steps until repetition. If more than 16 steps are set, the selection wheel can be used to switch to the next page(s). Pattern-Duplication Once you have created a pattern page, it is easy to duplicate it.
MD900 Pressing the UPDATE touch button updates the Devices list MIDI Settings (right). MIDI Devices If a connected USB MIDI keyboard is to be used, the USB device must first be linked (mapped) to a MIDI port (P1-P4). This allows MIDI Inputs the assignment to a part (A-D).
