Expanding the Mother 32 Part 2 - More VCO's & Chords, Vocal sounds, External Filter/VCF (Eurorack)

video upload by AJH Synth Official

"The last of 2 videos showing some ways to add more flexibility and sonic power to the Moog Mother 32 using AJH SYNTH modules. The synth is semi-modular and designed with Eurorack compatibility in mind, so this unlocks the huge range of modules in the Eurorack modular ecosystem. Since the Mother 32 has that trademark Moog sound, the AJH Synth MiniMod range sit particularly well with it's vintage analogue synth lineage. The individual elements of the standard MiniMod voice are in fact based directly on the original R.A.Moog version of the Minimoog.

This video shows another example of adding multiple external VCO's to create a big, dense tone with multiple octaves, and also with 2 of the oscillators offset at different pitch intervals to create chords, just as was possible on the original Minimoog synthesizer.

Also shown is an example of using an external filter, in this case the powerful GEMINI 2412 dual multi-mode VCF, which is simply a case of running internal and/or external oscillators and sound sources into the filter, then back into the Ext Audio input, setting the Mother 32's internal ladder filter to maximum frequency (fully open), and reducing resonance to zero. Of course there's no reason why this filter cannot also be used as part of a patch, although the Gemini's two filters can also be run into each other internally (Cascade = in series) in the same way. Finally an example of vocal timbres/formant sounds, which can be achieved by many methods, but here using the wave folder featured on the SONIC XV diode ladder filter, and the FIXED FILTER BANK 914, which really is a go-to tool for tone shaping, allowing the output of 14 individual filters (1 low pass, 12 band pass, 1 high pass), each fixed at a specific frequency, to be mixed together at individual levels in order to dial in a desired tone.
