Can Any body Tell Me How to Make Harmonium With Organ Or Other Caustic synthesizers ?
The subject line of your post made me think you were going to tell us.
I don't think you can with the Organ synth - I think you want a slow attack for a Harmonium and there's simply no way to shape the envelope like that.
I'm guessing that the subsynth may be the best bet with the LFO set to volume with a high depth and slow rate to replicate that pumping sound. Not sure what Waveform to use - suggest you draw one yourself maybe looking #5 and #6 below.
Given the complexity of the sound I think two Sub synths controlled by one Modular may help get the richness of tone you want. Alternatively find a Soundfont or samples and use the PCM Synth.
I think you probably need to just use samples in the PCM if you need something specifically harmonium. Playing around with the organ slider bars might get you something which isn't quite harmonium, but works on your track. Use your ears. Good luck.
