Eurorack CV Modulation Recorders

"Headphones on, please. This vid leverages the stereo image as part of the demo.

Modulation recorders are handy for coordinating modulation moves with a melodic or rhythmic sequence. You could also use a full sequencer, but in many cases that's overkill. These modules do the trick without too much complexity. (Though it must be acknowledged that the Voltage Block does market itself as a sequencer of sorts.)

These four all offer at least 3 channels of cv recording. Some are limited by steps in the sequence, some by memory. Also note that the level of quantization (simplifying the smooth recorded curve into something more stairstepped) varies from module to module. Lastly, note that they output different voltage ranges, which in some cases can be customized.

All work well for their assigned purpose, no duds here.

Source audio: Dixie II+, using an Morgasmatron as the target of modulation. I added a pulse from a second Dixie II+ to give me some rhythm to move along with. Modulation with no rhythm to it sounds a bit uninteresting in this context.
