TEAC IF-FW/DMmkII IF-FW/DMmkII v1.21 Release Notes - Page 4

Release Notes ªª Mac OS X Driver Stability V1.21 resolves a problem in which the computer could stop working. MIDI Timing MIDI Timing precision has been improved. Maintenance Items in V1.20 ªª Windows Driver Large Memory Systems V1.20 fixes a problem that occurred when using the driver on Vista64 with 4GB or more of system memory. Minimum Buffer Size V1.10 enforces the minimum buffer size, but the displayed buffer size was not correct for NORMAL Performance Mode. In V1.20 the buffer size can be set as low as 64 samples (1xFS rates) and 128 samples (2xFS rates). WDM Stability Stability when using WDM applications has been greatly improved, but Sonar users requiring full channel count must now use ASIO instead of WDM/KS. ASIO Stability Stability and performance when using ASIO applications has been improved. Control Panel When closing an application that was using the WDM audio interface, the control panel could sometimes remain in its locked state, with the buffer size, performance mode and WDM mapping settings greyed out. This has been fixed. Maintenance Items in V1.10 ªª Firmware This version fixes a known problem with loss of audio connection that previously required a hardware power cycle to recover from. ªª Windows Driver Latency In V1.00, there was sometimes a different latency between channels 1-16 and channels 17-32, and the overall latency could change slightly when the mixer and computer are re-locked together. V1.10 has the same fixed latency for all channels. Control Panel The Windows Control Panel has been improved since V1.00. •• If a WDM or ASIO client is currently using the IF-FW/ DMmkII, the Buffer Size, Performance Mode and WDM Channel Mapping settings are locked out and their control is grayed out. To change these values, first close all audio apps. •• WDM Input Channel Remapping has been removed in V1.10 •• The Control Panel now remembers where it was on the screen, and will open in the same position as the previous time, instead of always opening in the center of the screen. •• V1.10 now prevents the user from setting a buffer size smaller than the minimum buffer size, as those settings would always produce audio drop-outs or noise. ªª Mac OS X Driver Latency In V1.00, there was sometimes a different latency between channels 1-16 and channels 17-32. V1.10 has the same fixed latency for all channels. G5 compatibility On Power PC G5 machines, sometimes noise was present on the audio inputs and outputs. This has been fixed. FireWire When the FireWire cable is removed and the FireWire connection is broken, sometimes the mixer had to be powered off and on in order to regain connectivity. This has been fixed. Large Memory Systems Problems with large memory systems have been fixed. Stability Overall stability has been improved. Control Panel The Control Panel now remembers where it was on the screen, and will open in the same position as the previous time, instead of always opening in the center of the screen.
