Hi, everyone, I am here to report a fatal bug in OS 4, this bug can occur during live performance, it mutes the TI or get it noisy.
To see if your unit has the same bug, simply follow these step to do the test:
1, You need Ableton Live 8.1.1or greater, Max/Msp 5 installed. ( The demo version of Max/Msp is OK too, download it from http://cycling74.com/downloads/ )
2, Download the test file I made. http://www.megaupload.com/?d=4CI8J05L
3, Unzip and open the test folder, launch test.als with Ableton Live.
4, In the session view of Ableton Live, there are 4 tracks, the 4th track contains the MAX device.
5, Focus on the MAX device window, you can see "TI", "FM8", "Analog", right under each one of them, there is a small white box.
6, Click the FM8 or Analog box, track 2 or track 3 will play, steadily repeating C3 note.
7, Open the FM8 or Analog plugin window, just let it plays for a while, it is very stable.
8, Now click the box again to stop the FM8 or Analog clip. Click the TI box to start track 1.
9, You can hear the sound sometimes is not so stable.
10, Open the VC plugin window, the sound becomes more unstable.
11, Turn on VC's LIVE mode, the sound now is very unstable. Let it plays for 1 hour, it is probably get noisy or mute. Bug found.
12, Restart Ableton Live, do step 8 again, but this time close the VC plugin window, and minimize the LIVE window.
13, The sound is much stable than step 9, 10, 11.
14, Install TI OS 3.3.4, do the test again. The sound is stable, no bug found.
15, Please tell me the result, and also report to Access support.
Maybe someone think that the problem comes with the MAX device, let me explain: What MAX here do is stop and play the MIDI clip rapidly, just to make the bug more obvious, but not create the bug, it's just like a magnifier, takes us to a close look at the bug. Without the MAX device, the bug is hard to be noticed at most of the time, but when you can notice it, it kills you. Surely you maybe want to test the bug without MAX, then just open the VC plugin window and turn on LIVE mode, set the Global Quantization of LIVE to "None", keep sending MIDI notes into TI for 5 hours, rapidly stop and play, tweak the knobs, it has a high probability to get the bug.
Thank you everyone
