How to control "segment" from MIDI controller input

1

I want to control the argument of segment with MIDI input, but I am struggling to get the syntax right. I'm running into some type conversion issues.

Basic non-MIDI pattern:

d1 $ gain (segment 1 $ range 0.25 1 rand) # s "bd"

Then I try to replace the segment argument with a MIDI pattern:

d1 $ gain (segment (range 1 8 $ (cF 0 "90")) $ range 0.5 1 rand) # s "bd"

But this throws an error:

    • Couldn't match type ‘Double’ with ‘Ratio Integer’
      Expected type: Pattern Time
        Actual type: Pattern Double
    • In the first argument of ‘segment’, namely
        ‘(range 1 8 $ (cF 0 "90"))’
      In the expression: segment (range 1 8 $ (cF 0 "90"))
      In the first argument of ‘gain’, namely
        ‘(segment (range 1 8 $ (cF 0 "90")) $ range 0.5 1 rand)’

I've tried casting the MIDI pattern to type Pattern Time but it results in the same error:

d1 
  $ gain (segment ((range 1 8 $ (cF 0 "90")) :: Pattern Time ) $ range 0.5 1 rand) 
  # s "bd"

Any ideas?

Ah just needed to specify a "time" MIDI pattern with cT:

d1 $ gain (segment (range 1 8 $ (cT 0 "90")) $ range 0.5 1 rand) # s "bd"
