Korg mono/poly emulation

[thapoke]

Hello, I finally have a G2!

I have been trying to recreate my korg monopoly as I have to sell it.

The monophonic and arpeggiator modes are easy enough, but the paraphonic section is more difficult. The monopoly has 4 oscillators going through one filter and VCA with an adsr envelope each.

There are 2 problems

1.

In paraphonic mode the key assigner plays oscillator 1 for the first note and if that note is still held down it will play oscillator 2 , then 3 then 4...

If you let go of the first key held down it free's up oscillator 1 - so that will be used for the next key struck.

So the assigner will always play the lowest free oscillator that is not already held down.

I have not been able to recreate this using the status module or the counter - it seems to always assign a new voice and step through the voices in a random order depending on what has been played previously... it should always start on osc 1 then go to the next available oscillator that isn't held down already

2.

The envelopes can be set to retrigger every time a new note is struck or to have a single trigger on the first note.

Single trigger mode is easy using the mono keyboard module but multiple triggering using the keyboard module makes the envelopes retrigger both when you strike a key and when you release it - it should only happen on a key on event..

this thread has the same problem but i don't know if it was resolved.. http://srv4.electro-music.com/forum/viewtopic.php?highlight=paraphonic&t=30835

Any help appreciated!

this mono poly patch is in the archive but it doesn't work the same as a monopoly , keyassignements are random http://srv4.electro-music.com/forum/viewtopic.php?highlight=korg+mono+poly&t=4665

apologies this is in the wrong section, can this be moved to experimental patches please?

also I have been trying to get my head around the diy pattern appegiator building block which has a keyboard scanning circuit here http://www.electro-music.com/forum/topic-39414.html

- could this be used to make a 4 voice keyboard scanning/ voice assigner?

Thanks blue hell

Still trying to get this to work, I have got the multi trigger mode to work by sending a pulse to the fx section every time a new voice is triggered, which is getting closer to a monopoly in polyphonic multi trigger mode...

only the release stage of the amp envelope is triggered though, but this is an approximation of some monopoly patches.

If you've never played a monopoly try holding a 2 note chord in the upper part of the keyboard and then play a baseline - every new bass note triggers the chord again... or hold down a bass note and play different chords - every new chord triggers the bass note.... oh the joys of paraphony

still can't get the voice allocation to work in a predictable manner but I'm working on it...

Hi thapoke! Glad for you !

[thapoke]

killer patch

[Electromagnetic Wave]

I made another version to replace the sequencers used for tuning by the keyboard pitch output. Take less ressources. I added another osc, now 4.

I added lfo for each osc and some morphing with the modwhell on all 8 variations just for fun. After the 4 notes is pressed it's possible to just keep hold the last note from the chord. Usefull to tweak parameters with one hand when a chord is active.
