hey guys no big deal i wanna show you but i´ve just released a virtual emulation of the korg monotron. it´s some kind of the simplest circuit you can think of, just 1 (detuneable) sawtooth OSC, 1 sawtooth LFO, a switch for the modulation destination (either PITCH or CUTOFF), and a "virtual" ribbon controller. unlike the "real" monotron you can play the monoklon via MIDI in. sadly i could not emulate the most spectactular feature of the KORG monotron, the built-in KORG filter module(hardware version filter could be used for external audio , too) that is well known from the MS20... but this was just a small fun project for me and allthough i have no clue about filters and coding filters I KNOW that i can´t expect to find a virtual filter that sounds THAT great then the original... but perhaps someone of our gurus can help me out here hehe...perhaps it´s possible but i doubt that it is easy with SM.... i also want to include a optional drift feature after starting the plugin (senseless feature,just for fun, 😀 😀 ) because the original monotron does also drift a while before it has reached the initial state... just to imitate some "analog feeling" here lol.........

i don´t post the OSM here now because it is really THAT simple that you could easily create your own 😉 IF you don´t get the circuit just let me know and i will of course post the OSM. in a few days when i am back at home... just don´t have it here ATM... here is the link... comments and crtiticsm are always welcome... BUG reports are not really welcome but if you spot some bugs please let me know...

here is the link to 2 different VSTi versions (small and big GUI) and 2 standalone versions (also small and big GUI) http://www.box.net/shared/n8n9dd6k7e9mj27ivdqx

thx

Do you have a frequency vs phase plot?

Interesting keyboard action if you click and hold on the lowest note then move up the keyboard you can get about 4 octaves, then unclick and find your cursor on the other side of the screen. 😕 😕 😕

mhhh thanks for the hint, i have to fix this ... but i think most people are happy that they can play the monoklon via MIDI in, not like the original just with the ribbon. i mean WHO likes to play melodies with a mouse and a virtual keyboard on the screen? but, as said, thx for the bugrepot. BTW, here is the schematic. if somebody could help me adding a nice little "drift" option this would be very nice i made a start with it, added a counter /timer to the drift so that it automoatically becomes less and less after time but i don´t know how to combine the (mono)drift OSC with the(poly)OSC from my monoklon... ahhh and if somebody has a filter code for a KORG MS10 Filter laying around (lol) please share it with me hehe...

    Want to keep that track’s sound? Start a new song in SynthMaker first (Song › New song), then open this.
