Hi, Yoshimi is a neat repacking of ZynAddSubFX. It offers all kinds of interesting sound, but I call it musician-hostile. What you see is a bunch of controls that you have to manipulate with the mouse while playing, trying to read and understand the very small labels (on a modern high-DPI monitor) and try to get the sound, attack etc. that you want. It is next to impossible to perform this, so you will only try some of the 510 build-in patches, but you can't modify them easily. And modifying the sound while playing is essential for a good performance. In other words: Yoshimi is way too complicated. It would be more useful to supply only 10 patches that are easy to modify. Take for instance an ADSR envelope generator. In Yoshimi (and in most other software synths) there are 4 knobs that you must control. This is replicated from old hardware synths. Why not show a small diagram of the envelope, that you can modify directly with the mouse or with your fingers? The only animated visual component in Yoshimi is the output level indicator, which is the least interesting of all audio information. Why not think about the real benefits for the musician that software and graphics are capable off? The actual subject of my post was about algorithms to generate interesting and/or beautiful sounds. So, supposed you have just invented FM synthesis, then this forum would be an ideal place to write something like: "I found out that if you modify the frequency of a sine wave with another sine wave, then you can get very versatile kinds of audio signals. This method is simple and costs little CPU. See the following code snippets ..., or download my demo project at ..." Regards, Wouter Boeke On 08/28/2014 04:42 PM, Ralf Mardorf wrote:

My point is to add a vector control that is similar to the one provided by the Yamaha TG33, then you exactly would get a musician friendly control to edit sounds. People often can't imagine how effectively different sounds can be produced by recording a mixing sequence with a joystick, even if it only records volume and fine tune. There is no easier effective sound editing than to record a volume/pitch mix with a vector control. The joystick could be provided virtually by a GUI, as done by Alchemy http://www.camelaudio.com/images/ios/1-1-35/iphone/alchemy-mobile-iphone-1-… . Instead of using Yoshimi simply providing a MIDI filter that can record vector movements and store them and sends it to 4 other synth. The vector simply could send CC data for volume. IOW the MIDI filter, perhaps using the same CC as the TG33, IOW CC 16 vector x-axis and CC 17 vector y-axis are translated to CC 7 volume for 4 different synths and then is send to them. The MIDI filter will record the sequence of the vector control and MIDI channels of the 4 synth in presets. JFTR have you ever used a vector controlled synth such as the TG33?
