3. Set the desired sound with the controllers. Should you wish to switch over the volume
envelope between Release and Decay, press the ENV 2 button.
4. To store the current controller settings, press the STORE button. The program is now stored.
You can overwrite it as often as you wish, however.

1.5.6 Using the external audio input

The input signal is mixed with the internal oscillator. If this is not desired, the wave number must
be set to 99 (= no wave) via WAVESELECT. In the state of the system as delivered, it is also
possible to select program 99, which contains wave number 99.
In order for the external signal to be audible, the Syntrack must receive a note command, so as
to enable it to drive the VCA. This means that a connection is required at MIDI In, even if the
Syntrack is only being used as a filter.

1.6 Initial start-up

Use a MIDI cable to connect the Syntrack´s MINI In socket to your MIDI transmitting device
(master keyboard, sequencer, ...). If additional MIDI devices are to be connected down-line of the
Syntrack, use an additional MIDI cable to connect the MIDI Thru socket of the Syntrack with the
MIDI In socket of the next device.
If you wish to use the MIDI Out features (real-time recording of the controller movements,
dump, ...) connect the MIDI Out socket of the Syntrack with the MIDI Input of your sequencer or
your MIDI merger (device used to mix several MIDI data streams).
Connect the audio output to the audio input of your mixer, amplifier or similar.
Connect the power supply unit.
The display shows the number 01 (program). The MIDI channel is factory-set to 1. It must now be
possible to play the Syntrack.

1.7 MIDI control

Each time a controller is moved, the Syntrack outputs the value as a controller output via MIDI
Out. Program change commands and a Sysex dump are transmitted in the same way.
The system is able to receive and process the control outputs from the controllers (in some
instances MSB and LSB controllers), program change commands, aftertouch, pitch-bend, MIDI
clock, dump (Sysex) and system reset commands.

Cut-off frequency of the filter; 20..20'000 Hz
Also known as Q or regeneration. Feedback from the filter.
Modulation intensity of the filter envelope at cut-off frequency; positive of
negative, max. approx. 10'000 Hz
Decay time for the filter envelope; 0.01 .. 2.5 sec
Release / decay time of the volume envelope (ENV 2); 0.01 .. 3 sec. The
function is switched over with button ENV 2.
