Just in case anyone is interested, this venerable modular is on sale for $99 until the end of July. That's to me to be a bit of a bargain! Not the easiest synth to use but of particular interest to Eigenharp users is that it has a breath control module. On the Pico you need to remap CC17 to CC2, but other than that it works fine, though it's not always obvious how to optimally integrate the breath control module into some of the instruments (at least to me!), so some experimentation is required. The nice thing about Tassman is that it includes physical models in addition to other synthesis approaches and these can be combined together.
