The PSR740 lets you edit sounds a little at the keyboard - you can add effects but only three DSPs are available and you can only alter the wet/dry. The actual synth is similar to the MU80/100 (uses the same chips) and you can access the whole synth via sysex using XGworks, XGEdit or something similar. To take one effect, one of the basic reverbs which does White Room, Tunnel, Canyon and Basement, has the following parameters which can be changed: Reverb Time and Delay, Diffusion, Initial Delay, HPF and LPF cutoff, Width, Height, Depth, Wall, Wet/Dry, Density, Early Reflection/Reverb balance, High Damping and Feedback Level. Other effects have different parameters to suit. If that lot isn't enough to please anybody I don't what is. And you can cascade all five DSPs. As to sound editing, you can't add your own sounds but with 761 voices there's plenty to choose from. Each part or layer (which is one sound) has 61 parameters to choose from including vibrato, filters, envelope, pitch, LFO (frequency, phase and amplitude), tuning and aftertouch. I have some spectacular organ sounds which are done by layering six different organs, with each layer slightly off tune and at different octaves from the fundamental, and some white room reverb added.

Higher models like the 2000 and 9000 let you access a lot of this stuff at the keyboard because they have a superior display, but you still need the sysex to get at the whole machine.
