[chuck-users] STK instrument segmentation fault

[John Ellinger]

Hi Ge,

We met at SLEO. I'm using the newest chuck version: 1.3.1.2 (chimera) mac os x : intel : 64-bit.

Re: FM sound 
Yes I recall reading a forum message that FM was an abstract class. Maybe a simple output message could inform users they need to subclass FM.

Re: Brass sound
I recorded and attached a small example of the Brass sound I get (BrassTest.mp3). To my ears it sounds distorted. (chuck code at end of email).

Re: Mandolin
ChucK plays correctly and seg faults when finished. This happens consistently on my MacPro.  Here's a portion of the crash log.
