K1 VDS - Version 1.0 K1 Peculiarities ---------------- 1. The K1 System Exclusive MIDI implementation does not include individual parameter change messages for MULTI parameters. Therefore the entire patch has to be sent to the K1 everytime a parameter change is made. This accounts for the speed differences between the SINGLE and MULTI editors. 2. When a bank of patches is retrieved from the K1 by the VDS, the data is checked for accuracy using a checksum method. The K1 used in the development of this product sent bad data 20% of the time. If a message is presented indicating a receive error, retry the retrieve request. Additions To The VDS Manual --------------------------- 1. MIDI Channel Thru Option: 'TH' may be selected for the MIDI channel in the Sequencer dialog. Selecting 'TH' will will allow all MIDI channel messages to pass through the VDS unaltered. When the MIDI channel is set to '1' - '16' all MIDI channel messages are reset to the specified channel. This function was added to allow devices such as the Yamaha WX7 MIDI wind controller to send MIDI messages on more than one channel at a time. MIDI Channel Setting Result ------- --------------------------------------------------- 1 - 16 MIDI channel messages reset to specified channel System Exclusive messages sent on specified channel TH MIDI channel messages are unaltered System Exclusive messages sent on channel 1
