Using V-SCALE to compensate for the tuning/tracking problems on one of my Vintage Synthesizers, this time a Moog Micromoog from the late 70's. Also, showing how PRECISION VOLTAGES can also be helpful, and bringing the TAP TEMPO VC-LFO, CHANCE DELAY, and the MATRIX VCF into a short performance demo - FULL performance video by @DreamsOfWires can be found here: Moog Micromoog & Modular w/ AJH/MiniMod, H...
V-SCALE at its simplest will function as a highly accurate buffered multiple, but four of its five outputs are adjustable by way of multi-turn trimmers. These allow for very gradual adjustments to outgoing CV signals, so that they can be made viable for synths or VCOs that are not scaling properly.
Here I'm adjusting/modifying a 1V/Oct signal from a sequencer so that it controls my old Micromoog correctly, but it could also be used with incoming signals other than 1V/Oct, or even to correct am incoming signal which itself isn't scaling correctly or as desired. Each trimmer has an adjustment range of +/- 5%.
My Micromoog's tracking is so far off that it cannot even be corrected using the internal trimmers on the synth, so I'm using the Keyboard Output (KBD) as the CV input, instead. of the intended OSC input. This method bypasses the keyboard, so the keyboard voltage isn't added to incoming control voltages, and so doesn't interfere with it. The only drawback is that the root key will have to be changed to match the notes on a keyboard. That's where the PRECISION VOLTAGES comes in - it can accurately offset an incoming control voltage by semitones and octaves, either up or down.

The AJH SYNTH Eurorack modular range consists of high-end modules, all hand-made in the UK, most of which are based on classic, vintage designs, authentically recreating the circuitry of much sought-after analogue instruments and technologies of the past, whilst greatly expanding them, and bringing them to modern Eurorack levels of convenience, limitless flexibility, and reliability.

Check out the AJH Synth playlists for module 'User Guides', and 'Patch of The Week' videos, which will be either performances or 'how to' guides, detailing functions/methods, and a range of sounds, some familiar, some less so, containing a patch sheet at the end to show you how to construct it for yourself.
