Issues with timidity when running qmuvi #40

Open pelahi opened 1 month ago

pelahi commented 1 month ago

Description

When I try running the simple example 

import qmuvi
from qiskit import QuantumCircuit

circ = QuantumCircuit(2)
circ.barrier()
circ.h(0)
circ.barrier()
circ.cx(0, 1)
circ.barrier()

qmuvi.generate_qmuvi(circ, "bell_state")

I get the following

If I try running this command (ignoring the output) from timidity I get 

Try timidity -h for help

And it's version is 

TiMidity++ version 2.15.0

It is not clear what the issue might be (if it is a conflict in the version of timidity wrt instruction set produced by qmuvi) but I am unable to produce the expected audio output.

Gary if you have some suggestions I'd be happy to try them.

Hi Pelahi,

That is strange, thanks for letting me know. I don't have a mac atm, so it's a little hard for me to check.

Could you please try setting log_to_file=True in the generate_qmuvi method and send me one of the generated log files.

Hi Gary, Here's the extra output .
