2. Check, tune and calibrate
2.1 Check the assembled module
When the assembly of the module is complete, you should check that everything works. The following
steps will guide you through this process:
1.
Power the unit. You should see a light sequence on the SET and TYPE buttons. After the sequence
stops, the TYPE LED should blink at the LFO rate (that is determined by the MOD RATE slider).
Connect a MIDI keyboard via the MIDI to 3.5mm adapter, that is provided in the kit.
Press the SET button. The LED will lit. Press any key on the MIDI keyboard and then press SET again.
Now your MIDI converter is set to your MIDI keyboard's channel.
If your unit does not power up for the first time
, do the following:
A. Unscrew the small power board.
B. Plug the power board alone in the USB supply.
C. While it's powered, connect it to the module.
After this procedure, your unit should power up normally.
If not,
check the following:
A. Either your USB cable or power adapter are of a bad quality.
B. Your adapter cannot provide enough mA
C. You have done something wrong, during the assemble.
2.
Do the following connections:
- CV OUT (placed in the MIDI to CV section) to OSCILLATOR CV IN (both CV IN are identical).
- SAW to a monitor or somewhere that you can get signal.
WARNING!:
this is a very high signal level!
- Adjust the OSCILLATOR TUNE at 0% and the FINE at 50%. Now observe the SAW signal. Play
some notes on the MIDI keyboard and make sure that the pitch changes. Play with the TUNE slider
and FINE knob and observe the pitch changes. Then check the TRI and SQU outputs. Finally check
the NOISE, which will not respond to the change of the pitch.
3.
Remove the CV OUT to OSCILLATOR CV IN connection and then patch:
- MOD OUT to OSCILLATOR CV IN.
- Connect the SAW OUT to your monitor.
- Adjust the OSCILLATOR TUNE and FINE at 50%, MOD RATE 50%, MOD LVL at max. Observe the
change of the pitch. Move the MOD RATE slider and confirm that it works.
- Then press the TYPE button once. Move RATE up and down and set it at 50%. Observe the random LFO.
- Press the TYPE button again. Move RATE up and down and set it at 50%. Press any key on the
MIDI keyboard. Observe the envelope modulation.
- Press the TYPE button again. Move the Modulation wheel of the MIDI keyboard. Observe the
change of the pitch.
4.
Remove the MOD OUT from the OSCILLATOR CV IN connection and then patch:
- The ENV OUT to the OSCILLATOR CV IN.
- The G OUT (placed in the MIDI to CV section) to the ENV TRIG IN.
- Set the FALL at 50% and the LVL at max. Press any key on the MIDI keyboard and observe the
change of the pitch.
5.
Remove the ENV OUT from the OSCILLATOR CV IN and the G OUT from the ENV TRIG IN and
then Patch:
- The LFO OUT to the OSCILLATOR CV IN.
- Set the LFO RATE at 50% and the LVL at max and observe the pitch changes.
- Then set the MOD with the TYPE button on the LFO mode and patch the MOD OUT to the LFO CV.
Adjust the MOD RATE at 50% and observe the change of the pitch.
