anyone know how to use nysthi mono recorder?

I want to record a simple wav file. Seemed like NYSTHI mono recorder would be a good choice. But it seems semi random in terms of when the start and stop buttons are active. How do you use this thing?

Or conversely, what’s a good module to use if I just want to record a simple wave file from inside VCV?

ah - of course - the VCV recorder will do this, and is easy to use. yes? what module will play back a wave file in VCV (that is easy to use)?

Play or Player, by cf are some I have used in the past and were pretty neat, especially Play which is quite small:

Ah, cool. Thx!

VCV Recorder brings the best quality I know
