Seq that outputs freq instead of notes?

Is this a thing? Basically I want to find a sequencer that you can dial in say 437 followed by 567 and 921 and it will output that specific pitch instead of usual sequencers that will only play notes that are tied to the usual scales.

One solution that comes to mind would be to use Scala with instruments that support it:

I don't think the list there is complete, btw.

Another option would be to use something modular like Plogue's Bidule, though that would still require the use of instruments that support alternate tunings, or making your own with the tools provided.

you could do this by stepping through a sequential switch fed by "constant" modules in bitwig's grid (you can type note names, frequencies, or even ratios into most pitch params and have them automatically spit out the correct CV to make what you're after)

Pitch to Midi translation would turn any sequencer into such a thing. But you need frequency to pitch conversion (the inverse) to find the correct pitches to place into a microtonal sequencer... I could do both in Bitwig, but its easy in Max/MSP (which would allow to create such a sequencer directly) or Max4Live as well... The Max objects are called mtof or ftom. In Bitwig I made my own patches in the Grid...
One "sequencer" I know of is the ancient UPIC from Iannis Xenakis. There is an app for iOS and Mac/Win from my friend Rodolphe Bourotte which implements a sort of UPIC but has a logarithmic presentation and shows it as pitches:

this looks very handy - even the free one which I will try first. And I have to check if all my main instruments are MTS or MPE compliant
