I have just posted the Nocturne (2nd movement) of my 3 movement suite for Ondes Martenot, Celeste, Harp and String Orchestra. Listening time is 3:30 min.
All except the Ondes Martenot were done with GPO, the Ondes sound is the one supplied with the Sibelius 3 program. It is a "plain vanilla" sound, but gives a good idea of its timber for this mock up.
If time permits in the next few weeks I will try to post this movement with a real Ondes Martenot playing the solo for comparison.
I also hope to post the uncompleted 1st movement shortly.
Hope you enjoy it
