_________________________________

1. Rejecting all sample rates below 32kHz on Delta TDIF (since this is WDM those

channel mask = 0). Under W9x copying can't be avoided.
  
2. ControlPanel Logos changed from 24Bit truecolor to 256Bit indexed color to save download 
time (from 915kB to 400kB)


Ver: 5.12.1.13   Date: 04/26/2001
_________________________________

1. Include support for Delta TDIF

  are played
  (no manual settings of the control panel needed), automatic resetting to
  prior state afterwards

8. rate locked state not saved fixed


Ver: 5.12.1.12   Date: 04/12/2001
_________________________________

1. This is an internal test version for W2k only. It is not throughoutly tested! Under 
WinME the system mixer is broken: You'll be able to install and run the drivers but you 
can't access the system mixer/volume sliders. 

2. Multi stereo I/O: in addition to the Multichannel interface the driver exposes stereo 
interfaces like "1/2 Delta-1010","S/PDIF Delta-1010". Due to the 10 device limit in W2k 
only the first 10 devices will show up in any MME application. 

3. Control Panel ver 1.02.02 like in Dougs newest driver set.

4. True Multiclient support: ASIO/EASI and WDM ports can be opened simultaneously. If the 
same out channel is used with ASIO and WDM, sounds get digitally mixed in the driver. 
Input channel signals are distributed to both apps. In the Control panel you can now only 
select common latency in terms of ms. The buffersize for ASIO/EASI is calculated using 
the currently selected samplerate. If you change the samplerate inside the asio-application,
the latency will no more match the value set in the panel. 

5. Delta TDIF support: The latest TDIF startup code (ver: ftdif03d.bit) is included in 
the delta.sys binary to keep the driver OS independant. This version is intended to test 
the TDIF-Bus functionality. SPDIF/Analog monitoring is working but i get loud click 
sounds when opening the Control Panel, have to look at this further. 


Ver: 5.12.1.11   Date: 03/21/2001
_________________________________
