Monotron-Über-Mod

Der kleine Korg Monotron ist von Werk aus so konstruiert, dass Modder und Bastler besonders leicht Hand anlegen können. Das liegt unter anderem an extra frei gelassenen Lötstellen auf der Platine. Nun tummeln sich genau aus diesem Grund etliche Videos von umgebauten Monotrons im Internet. Dieser Mod hier sticht die meisten von ihnen aber in Sachen Umsetzung, Features und Gehäuse um Längen aus.

Features:

– MIDI Control – using the MIDI-IF kit.

– Re-Enable the Ribbon

– CV Control: Simple mod due to the solder points on the Monotrons PCB.

– Pulse Wave: Using a comparator, a pulse wave is created from the Monotrons saw wave. The comparator has a control for the width of the pulse.

– Sub-Oscillator 1 – A second comparator is used to generate a square wave that clocks a 4040 divider. The first output of the divider is an octave below the sound source, and is used as a sub-oscillator.

– Sub-Oscillator 2 – The second output of the 4040 divider is two octaves below the sound source, and is used as a second sub-oscillator.

– Overdrive

– Envelope – a simple AD envelope control to the filter that can be toggled on or off.

– Power – a 7805 power regulator that uses a 9V DC adapter. No more need for batteries.

– Tuning – volt/octave tuning trimpot was moved for accessibility.

Gesamtpreis des Mods: 150 US-Dollar
