the issue is not scope which can send signal that are CV compatible (through a converter of DC coupled audio).
The issue is calibration of different converter / oscillators/ gear etc.
For example, a DC coupled audio interface (or a eurorack DC coupled mixing module) does not mean it is 1V/Oct: will not translate signals the same as a proper digital to CV board made for 1V/Oct. However, Calibration is mainly required only for pitch control (where a digital C note is translated as a C note in the 1V/Oct range). Fo rfilters or unpitched signals, you generally don't need 1V/Oct.
For example, you do not need any digital-to-CV converter to use scope modulators with A MS20 filter or envelope triggers, as this is taken care of by the MS20 "ESP" section. However, you will be very frustrated if you use this signal to control the MS20 pitch. The signal will modulate the pitch, but you will get nowehere in terms of pitch control.
So DC coupled audio is not the same as 1V/Oct or (or 1 Hz/V in the case of the MS20) in terms of range/calibration.
A keyboard outputs 1V/oct, an oscillator pitch needs 1V/Oct, an LFO does not need that, it uses audio range.
So it is more about your own requirements and the type of gear you need..
Also, DSP to CV is not the same as CV-to-DSP and I still need to find out if it is same or different than CV-to-Audio.
You could use eurorack modules if you have that (mixing/multiples that can do audio or CV), or other CV-to-audio converters (I think expert sleeper have that).
Again it is only for pitch. If I want to use a eurorack oscillator with LFO functions, I Just need to plug it as an audio signal and it works directly, and it will modulate anything. Good enough for filters or triggers. Not interesting for pitch.
On the SpaceF front, I would like to add the dsp-to-DCoupled audio but I need to do it in a proper eurorack mixing module, which is not available right now (and
are all mixing modules reliable ie will output exactly 0dB attenuation at max position (and not -0.0001 dB for example) ? not sure at all - and this would make a difference in the digital world). However, if it is the same as with the Korg MS20, this is totally useless in terms of pitch control. And it is expensive (more than 50 euros for a mix module that give you 1 output = 400 euros for 8 outputs!!!). The Expert Sleeper ES-3 is really the best in terms of price per output (it is around 200€ for 8 CV outputs). Once you have that, you don't need anything else, except a second ES-3. (The ES-3 is adat to CV, there is another model that has CV-to-adat/audio).
Also, generally the digital signals are calibrated for native software, so to use inside Scope you need +/- 12 dB to get the same between dsp and Native: for example: KrOn DSP Pitch table can control Native Modular Racks (Voltage, VCVV...) once you put the master out to the max, ie +12dB). The pitch of native devices is Scope pitch+12dB.
For the Arturia stuff, i don't think they are limited to CV and you can use them with midi. So you don't need anything to start working with them. Ok, midi and CV is really a different feeling and you will never acheive with midi all that you can do with CV. But also, the receiving devices must be adapted to working with CV signals, which is generally not the case with software (for example, VSTi cannot have extra inputs for modulations, they can only have 1 midi input, unless they are categorized as effects (effect can have a sidechain input as well as midi), which makes them more cumbersome to use. So you would need to use Midi CC, which is unprecise.
I have the keystep "not pro", and the sequencer sucks in terms of functionalities and playability. I tried to use it, but it is unuseable. The demos of the beatstep pro look much better, but I don't have any experience with that. In all case, you will have some work, and there is not device or module that will translate what you have in mind without a little bit of involvment on your part. Youtube videos are sexy, but for many video makers, it is business for more views and free gear.
Various random modes are coming to KrOn very soon
the only hardware i would add is something like an ableton controller and learn ableton (and buy it because i don't have it lol). As said above, for modulators *from* hardware, it depends on the type of modulator and there is no general rule. It depends on the maker of each hardware. There are a couple of KrOn users who use Eurorack modulators the other way around. You must ask them because I am not going that way (too expensive for me
) .
