Try Csound with simple notes

Select the "Data" window and type cmd-o to load "-da.tryCsound" in the examples folder. On top of the "Data window" the instruction


tells BP2 to immediately load the "-cs.tryCsound" file describing the orchestra. Since no "-mi.<name>" is attached, musical items will contain only simple notes, and Csound scores will be based on the conversion of MIDI messages.

Select for instance the sequence of simple notes

A4 G4 C5 A4

and type cmd-p ("Play selection"). This item is played on MIDI and immediately saved to a Csound score file containing:

t 0.000 60.000
i2 0.000 1.000 440.00 90.000 0.000 0.000 0.000 ; A4
i2 1.000 1.000 392.00 90.000 0.000 0.000 0.000 ; G4
i2 2.000 1.000 523.25 90.000 0.000 0.000 0.000 ; C5
i2 3.000 1.000 440.00 90.000 0.000 0.000 0.000 ; A4

Each line starts with "i2" meaning that instrument 2 is used. BP2 found this value in the settings of instrument 2:

Assign as default to channel 1

and MIDI channel 1 is the one used by default.

On each score line, the "2" of "i2" is the value of argument 1, the leftmost one. The next two arguments are always assigned to the on-setting date and duration of the event, measured in beats. Then comes argument 4, which in this example is assigned to pitch, here in cycles per second. Argument 5 is the volume (range 0..127) set to 90 by default. Arguments 6, 7 and 8 are used for another parameter not demonstrated here.

Instrument 2 does not accept any other parameter. Therefore, velocity, pressure, modulation, etc., assignments are ignored.
