Hi Trevor,

I am currently working on building a simple Csound to score conversion tool using Abjad and have encountered an issue. I find Abjad particularly interesting for this purpose.

I’m using a simple trick in order to obtain some notes from onset, pitch and duration variables: s4*##e{onset} {note} 4*##e{dur}

When I’m trying to use this syntax inside a Abjad I'm facing a problem:

  File "/opt/homebrew/lib/python3.11/site-packages/abjad/parsers/scheme.py", line 340, in p_variable__IDENTIFIER

    raise Exception(p, "AAA")

Exception: (<ply.yacc.YaccProduction object at 0x102e3a410>, 'AAA’)

I think that the issue is that it cannot parse the ‘##’ symbol, am I right?

Do you know a way to solve this?

Your help is greatly appreciated. Thank you in advance for your assistance.

Best regards,

The code:

import abjad

onset = 1.14

note = abjad.Note(60, (1, 2)).written_pitch.name

dur = 3

voice = abjad.Voice(f's4*##e{onset} {note} 4*##e{dur}')

staff = abjad.Staff([voice])

score = abjad.Score([staff])

abjad.show(score)
