I am trying the various examples with various plugins via midi out, and I am puzzled by MtxFugue7: I muted seq 1 and it seems that seq 2 generate two notes at each event, but there is no chord active... Same with seq 3...

How is that possible ?

HI Antoine

Hmm. I take it you have muted sequencer 1, and turned chords off on sequencer 2, for the mtxfugue7 snapshot? At 1/16th tempo it may then appear there two notes start at each step, because DURATION is set to 2.

This means the prior note is sustained for twice the period of a sequencer step period (at 1/16th clock rate, 1/8th), due to DURATION being set to 2.

So at each step after the first, the prior note is still playing, which may make it sound like two notes are starting at each step. True, with chords off, there are two notes playing from the channel, but only one note starts at each step.

There's a simple way to check it. In the clock section, if you just turn the SLOW button on, then the notes period is much longer. Then it is more obvious the prior note is sustaining over the current note.

In fact with chords on, sequencer channel two 2 plays six voices at all times; and with channel one also unmuted, channel 1 then also plays notes with a duration of 2. So Husserl may actually play up to 12 voices at one one time from the two sequences in channels 1 and 2, depending how much the chords from the two channels coincide on the same notes.

But when I record the midi out, I do see two notes starting, not one note sustained and the other starting in the middle of it...

Is it because of the stepfilter which chops the beginning of the 1/8th note and makes it a 1/16th note ?

Hmm. I looked with MidiOx. At first I thought I was getting the same thing, but I hadn't muted the parallel notes from sequencer channel 1. With chords off, I only see one note-on event for each step from sequencer channel 2. There are additional notes playing in parallel from sequencer channel 1. Did you mute channel 1 beforehand?

By the way, on this snapshot I was going to add additional matrix modulations originally, but I found the sound so pleasing without the matrix modulation, I left it as it was. It is a nice sequence, isn't it?

Yes I muted seq 1. In fact I now systematically solo seq 2 or seq 3, and usually on seq 2 the first 2 or 4 notes are single and then they always come by 2, and on seq 3 they alternate 1, 2, 1, 2...

Now from time to time when I first load husserl I get the right pattern with only single notes. I tried to save this snapshot and reload it when I get the double notes, but in this case I still have the double notes. It looks like when I start getting them there is no way of getting back to the correct state save by reloading the ensemble (and even then it is not clear it always work).

I also noticed that if I increase the tempo of seq 2 to 1/16 instead of 1/8 I never get the double notes, so it seems to me there is something going on with the parallel sustained notes and the step filter and the pattern is hyper sensitive to the timing and easy to get aligned to a sequence of double notes rather than single notes, but I can't nail it and systematically reproduce it

I'm very sorry I must have confused you. In my hurry to reply I looked at mdFugue7 instead of MtxFugue7. On mtxfugue7, the multiple notes are meant to happen, because the length of seq2 is 8 notes at 1/8 tempo, and seq1 is clocked to trigger a new fugue on seq2 at 1/2 tempo. So when the second note from seq1 starts a new fugue pattern on seq2, the previous fugue pattern is only half way through. The prior fugue continues to play in parallel while the new fugue starts.

The step filter's highlight ring highlights the most recently issued notes, so when the second fugue starts the step filter's highlight ring moves back to the first step, but the previous fugue pattern on seq2 is still running in the background.

To hear more clearly what's going on, you could try these things:

* increase the tempo of seq2, or reduce the tempo of seq1.
* First turn off the step filter and set the groove to zero. Then try reducing the pattern length to 4 or less, so the patterns don't overlap any more.

Now you're ready to increase the pattern length, or slow the tempo again, so the notes from consecutive fugues overlap again. Listeners won't know what's happening and will be very impressed by the chord complexity!

Note, you can also transpose all current notes via the pitch modulation matrix, for example, you could transpose the overlapping fugues from a MIDI keyboard, and/or in another clocked pattern. Amazing, isn't it?
