JUPITER-Xm: When I select JUNO-106 and SH-101, turning the OSC [TYPE] knob does not change the type. Why?

This is because the JUNO-106 and SH-101 do not have the concept of oscillator waveform selection; they are a type of synthesizer that lets you design the sound by adjusting the volume of (or turning on/off) PW (square wave / pulse wave), SAW (sawtooth wave), SUB OSC (sub oscillator), and NOISE (noise).

Use the following procedure to design the sound:

1. Select JUNO-106 or SH-101. If you want to start editing from the simplest possible sound, use “TONE INITIALIZE” to initialize the tone.
2. Press the [FUNCTION] button, and then use the [1]-[4] buttons to select the waveform that you want to adjust.
   • [1]: PW (square wave / pulse wave)
   • [2]: SAW (sawtooth wave)
   • [3]: SUB OSC (sub oscillator)
   • [4]: NOISE (noise)
3. Use the OSC section’s [LEVEL] knob to adjust the volume (or turn it on/off).
