Haven't tried it yet, but if you need the opamp only for audio, the
TL072 it's not much of a problem if you take the recommended pratices to
avoid this nasty behaviour (compensation capacitors, etc).

OTOH, the TL series won't work like the 4558 / 1458 / 741 in some types
of effects devices (like distortion units) and many other synth
circuits, no matter how you try...
