Some questions regarding Hapax <> Eurorack

[Maarten]

Hi,

I currently have some semi modular synths and am thinking about expanding on them a bit more with a few modules.

Before I buy anything, I do have a few questions:

1. I think it is possible to use Hapax as a CV processor, for example: send CV to Hapax CV input, then make Hapax (using the fx matrix) attenuate the CV signal and send it back to one of the CV outputs. Am I correct that this works? If so, what latency does this add to the CV signal?

2. Does the Envelope fx with the output set to CV out actually replace the need of a dedicated eurorack envelope module? Can I just send an envelope from Hapax to a eurorack filter mod input and it just works? Is it snappy enough to create plucky basses? Any caveats?

Yes

In both cases, it depends

@Thibault_Squarp

Regardless of the ‘destination’ (CC, CV, etc.), you can store 1 data point each clock tick.
At 192ppqn (192 ticks per quarter note), you’re looking at a sampling time of 2.6ms at 120BPM, so about 384Hz sampling frequency, which according the Nyquist Sampling Theorem means a maximum frequency of 192Hz can be captured.

Using Hapax as a CV processor can, depending on your application, result in a few milliseconds of lag, and/or “blockier” signals, akin to a (admittedly very fast) sample-and-hold.

Ok thanks! Sounds very reasonable
Will have to try and see if it works for me.
