1) Connect the AC adapter cable to the power input jack, in the back of the
controller, located next to the power switch. See Figure #1.
Make sure that the AC adapter corresponds to the correct voltage output. The
Studio 900 will accept an adapter that has a rating of 9V DC with a positive polarity
tip and has a minimum current of 200 ma.
2) Connect MIDI cable from the ST-900 s MIDI outputs, (each output can handle up
to four synthesizers, modules, or effect devices) to the MIDI input on your sound
sources. Set your sound sources to the desired MIDI channels by the ST-900. Each
channel would normally be assigned to a different sound or effect. Since the ST-
900 has only one zone, you can only program one of the l6 channels at a time.
Make sure that your sound source is properly assigned to the channel you are
sending on.
To select a base channel hold the [CHANNEL[ switch and enter the channel number
(1 through 16) by depressing the appropriate black numbered key (0-9). The
function switch must be released after the black number keys. At this point the ST-
900 is sending on that channel.
Program change:
A program change command allows you to change the sound on your sound
source from the ST-900. The program change will be sent on whichever MIDI
channel the ST-900 is currently set. Program changes are numbered 1 through 128.
You may notice, depending on the sound source, that a program change of 1 will
show up on your sound source as 0. This is not a problem, since MIDI is not
completely standard between manufacturers. Thank the heavens that there are only
a few anomalies like this between the manufacturers.
To issue a program change, hold the [PROGRAM] switch and enter the desired
number on the numbered black keys with the appropriate program number or use
the [INC]/ [DEC] (increment/ decrement) keys. If a number greater than 128 is
entered, it will wrap around to the beginning.
Bank change:
Some sound sources today, especially found on computer sound cards, have a
feature called bank select. The MIDI specification calls for bank numbers 1 through
16384. Once you have selected your bank you are able to select a program change
(1 through 128).
