Invert LFO
#1
Hi, and thanks for creating this great device!

Would it be possible to have an "inverted" option for all LFO shapes in the mod matrix?

For example, if I'm in G major and using LFO-3 set to square at 16 beats I can have slot 1 modulating Chord Degree between 0 and 1 and slot 2 using the same LFO modulating Chord Type between 1 and 5 - this gives me a simple chord sequence alternating between Gsus4 and A7 (the opposite of what I initially expected, but I guess that's because a Type change only comes into effect when a new Degree is selected, and with the LFO the two events are firing simultaneously). If I wanted to alternate between G7 and Asus4, I'd need to be able to invert the LFO in slot 2.

My ideas are that you could either double up the number of options when selecting a Mod Source ("LFO-1 Inv", etc.) or make it possible to select negative values for MOD AMT - so with my example a DEST VAL of 1 and MOD AMT of 70% gives a Mod Range of 1 to 5, but a MOD AMT of -70% would result in a descending Mod Range of 5 to 1.

I'd be interested in your thoughts on feasibility, and fully appreciate from my own endeavours what it's like to have a user "imagine it would be easy"!  Wink

Its late and I'm having trouble thinking... but first thought would be for a more specific sequencing of the chord and type, use patterns as a mod source. In the future we'll have a chord sequencer on The NDLR, and this would make it a lot easier. Definitely easier than implementing bi-polar LFOs. I'll have another look at this with Steve and see if there's other solutions.

I wish it was finished now... but the Chord Seq'r will fix all your issues, there is on going work on this feature.

In the mean time you can use the alt1 or alt2 chord types which will predicatively change the Chord Type.... 
or non-predicatively set the S&H wave shape to the Chord Type at a slightly faster freq than the Chord Degree.

Thanks both! I shall wait patiently for the Chord Sequencer - plenty in this box to keep me occupied until then. Smile
