Improving Intonation using the AJH Synth V-Scale

Improving Intonation using the AJH Synth V-Scale

One of the potential challenges of using a modular synth is keeping multiple VCOs in tune with each other as well as external instruments as you play up and down a scale. Most VCOs have trim controls to improve their tracking, but they can occasionally be frustrating to use: They may require you to remove the module from the case to access them, or the manufacturer might have not have used high-precision multi-turn potentiometers for the trimming controls. Therefore, I’ve added several AJH Synth V-Scale Variable Precision Buffers to my modular cases, and have been happier for it. What sets it apart is that 4 of its 5 outputs have high-precision trimmers accessible from the front panel, allowing you to improve the tracking of connected modules like VCOs and resonating filters.

When Do You Actually Need a Buffered Multiple?

When Do You Actually Need a Buffered Multiple?

A perennial question is “do I really need a buffered multiple to connect to my oscillators?” The correct answer is “it depends” because there’s so many variables with the way different modules were designed. I figured it was time to flesh out those details so it didn’t seem like so much voodoo.
