Simultaneous MIDI and Audio outputs on playback of MIDI File

Dear Friends :

This is a request from a home-grown self taught musician from India, who is into electronic music and Hymns / Songs for Church Programmes.

1. I have recorded Midi Song Files including Accompaniment / Melody / Rhythm, using a variety of Yamaha Keyboards as follows :
1.1. using the built-in record function (PSR 630 – on floppy disk)
1.2. using the built-in record function (PSR 900 – on USB)
1.3. on a Laptop using the MIDI input / output via a UM1 Edirol MIDI interface cable, using Cakewalk Music Software, from a PSR 48, PSR 500 and other Yamaha Keyboards.
2. All the songs have been edited on Cakewalk Music Software.
3. All the songs, recorded as above, when played back through the computer produce the following output :
3.1. If the Midi Output is set to “Microsoft GS Wavetable SW Synth” then the entire range of the recorded tracks is reproduced through the laptop speakers
3.2. If the Midi Output is set to “UM1”, then the tracks play true only if the UM1 cable is connected to the original keyboard on which it was recorded. i.e., a song recorded on the PSR 48 produces some discordance if the UM1 is connected to any other keyboard. The commonest problem is that the MIDI output triggers a sync-start of whatever Rhythm is currently set on the playback keyboard to. There are other problems too.

4. My query
4.1. Can I obtain the AUDIO signal through the Laptop speaker output AND the MIDI signal through the UM1 cable output SIMULTANEOUSLY.? Right now this does not seem to be possible. It is either this or that.

5. Rationale for the requirement
5.1. I would like to do stage performances using the recorded sound as Karaoke Backing Sound Tracks, being played on either the original Cakewalk or your SION software, through the “Microsoft GS Wavetable SW Synth” output port.
5.2. If I can then simultaneously send the MIDI signal to a DIGITECH VHM-5 Vocal Harmonizer, through the UM1 cable MIDI-OUT port, set the Harmoniser to produce harmonies based on the chords played, I will be in 4-part harmony bliss.
5.3. If there is alternate software that can produce these dual outputs simultaneously, please let me have the details, to enable me to get relevant information as fast as possible, and familiarise myself with the same.

Please respond directly, or forward this to whoever you think may be able to help. I will be happy to consider buying software/hardware from your range if I am sure it will do what I want it to do, as above.

Thanking you in advance
