There are currently 13 different devices. The important (kick/snare/hi-hat/tom) as well as the exotic (Kplus and FM) are all represented. “Kplus” is called this way because here the “Karplus-Strong” synthesis is used – David Zicarelli (CEO of Cycling ’74, the creators of Max) jokingly said that this was also the best and only purpose of this synthetic form… Basically, most important for me, next to the sound, was a very dynamic control using velocity data – therefore, this section is quite extensive in every device and almost every parameter can be played dynamically.
Great stuff. Be sure to check out the screenshot of the inside of DrumSynth, especially if you’ve never seen an intimidating Max Patch before.
