linear/expo conversion?
Hi to everyone here!
new to Drambo and completely in love, im even returning my new oxi one, and will write my project/liveset in drambo!
so, I have 2 old vintage ms20's that I love, and id love to be able to sequence them, but they use hz/v rather than the standard volt per octave...
the formula ive seen written is something like:
hz = 55 * 2^(volts+.25)
I have a disitng NT on order, that hopefully will have the convertor algo in eventually, but ive seen drambo has a lot of maths functions...maths isnt my strong point..
the disting NT has -+11v on its outputs so thats good..
do you think a linear to exponential conversion is possible on cv's being output from drambo?
any clever people here care to help???? hahah worth a shot!
cheers

In dRambo under "Utilities" there are two modules,
"CV to Freq" and "Freq to CV" which you could try using.
I think the former rather than the latter would be useful for you,
I don't anything Hz/V to try as all of my stuff is 1V/Oct.
And welcome.
thanks, ill give those a go when my patch cables arrive :) nice one
Interested to see how you use it in your live set, do share some videos if you make any
I haven't dealt with this conversion before, but you can definitely create that formula in Drambo with liberal uses of the math modules.
I don't think it's possible to do this with the math modules. The Exp module for working with exponents is extremely limited. The Exp module takes input from one signal. The value of the output signal is calculated by the function
e^x, where e represents the constant ~2.71828, and x represents the input signal. You cannot do base 2 calculations with the Exp module.As for the Freq to CV / CV to Freq modules, check out this thread for a good explanation on how they work: https://forum.beepstreet.com/discussion/comment/51981/#Comment_51981
thanks so much! I will try using standard v/oct output to an external linear/expo convertor and see how is goes, thanks for taking the time to explain a bit!
abssolutely!
Oh woops yea you're right, I forgot about that.
