maelzel's Issues

Mac .show ?

Hi Eduardo,

Just trying to test maelzel and in the first exemple got stuck with this:

from maelzel.core import *

seq = Chain([
    Note(60),
    Note("c#4+"),
    Note("4Eb"),
    Note("4E+20"),
    Note("4G-10hz"),
    Note("442hz"),
])
seq.show()

Error:

Default path for soundfonts only defined in linux
The file /Users/mypath/Library/Caches/tmpm9x0s0g0/4_dexb2d.png does not exist.

I am on macbook M1 Pro, Sonoma 14.4.
