I’ve had this incredible sequencer for a few weeks now, but there’s just one problem: the groove.
Alternating between 5 and 7 is already more than enough for my taste. I’d like to be able to replicate the 1–10% range available in the Master Swing on individual tracks..
Having swing only on the Master is really too limiting for what I’d like to do
Does anyone know if there’s a way to achieve this?
Thanks a lot!]]> Hi everyone!

For Nerdseq it'd make perfect sense to do this with simply pressing shift on a cell and that value would now be the 'last value' for when you enter values.
It makes editing very fast and fluid, and I feel myself constantly reaching for it!

Maybe something similar already exists, I couldn't find it in the manual, if so let me know.]]>

It would be great, quicker, if you have the Video I/O with a USB keyboard to be able to type an effect name name in the pattern editor, rather than have to use the various scrolling options with the cursor buttons. 

Likewise with most of the other UI. To be able to just be able to type numbers in, just like the various Amiga Tracker programs, would be a lot quicker from a productivity point of view.

Thanks,

I'm syncing via USB host through Project > Clock IN > MIDI USB-Host.

Whenever they stop anything, such as a loop, my Nerdseq stops, even though other loops continue running.

Whenever they start anything, my clock starts again.

I would like to be able to control at least stop myself, and preferably also start, while still being synced to an external MIDI clock.

I really appreciate the new feature "user harmonics from MIDI keyboard", it opens a whole new world to me.

Could you add a multi-octave quantization mode ?

So it would be possible to quantize to less notes in the lower register (like only the root in the lower octave, then add the fifth in the second octave, and more notes in the higher octaves).

Best regards,

Martin]]>

The Midi track type does have an indicator thus for the sake of consistency can you consider adding visual indicator for all track types when they are active.

I was thinking in terms of a little red dot that blinked in time with the track steps?

Thanks for considering.

Currently, the NerdSEQ appears to send the voice-specific form of the I²C Note On/Off protocol.

The Disting NT also supports the MIDI-like Note On/Off commands, which let the disting perform its own voice allocation (round-robin, voice stealing, etc.).
For instruments like the disting NT's Poly Multisample algorithm, it actually seems to not be able to trigger at all unless you send a custom note command (54,55,56)

I am trying to set up a way of externally jumping to next / previous sequencer row (with patterns on them).

Currently STRW only accept a hardcoded row number (RV00–RVFE). It would be very useful if it could accept a variable or row result as the destination row (perhaps a version of STRW under GLOB) – similar to how SLCT can select a track dynamically via VA..VP or RW00..RW45.

This would allow building a simple next/previous row navigator in mapping using a counter variable incremented/decremented by a button press, making live performance navigation much more flexible.

Thanks for considering!

---

Additionally, it would be very useful to have a mapping source that returns whether a sequencer row has patterns assigned.

A source like RHAS (Row Has Assigned Patterns) that returns a value 1-8 reflecting how many patterns the targeted sequencer row has assigned, and 0 if it is empty. This would allow conditional navigation – only jumping to a row if it actually has content, making it possible to skip empty rows automatically when navigating forward or backward through the sequencer.]]>

After a short while all output I2C freezes.

I can confirm in Disting NT, that it stops receiving I2C.

Nerdseq is still showing an output is sent inside mapping setup.

I found it with a more elaborate calculation in mapping setup, but it is also happening with the following setup:

I don't know if this is achievable, but I feel like it should be.

Connecting a Linnsturument through the Multi-IO and using the TRS-A Out to a Disting NT would be such a dream compact setup, but I can't get the pitchbends to not bend every note even though they're being transmitted on different channels (?).

I'm not an expert on this, so not sure if my terminology is off a bit.

In the midi setup on the Nerdseq, I have Host Channel 2-9 (Linnstrument 2-9 are the Per Note Channels) all set up to send to the same track.

I can play the Disting polyphonically, but bending any note also bends every other note. I'm not certain if this is because the Nerdseq track itself kinda "smooshes" the forwarded channels together in order to forward the 8 incoming channels to the 4 outgoing.

Anybody have any ideas on how I could set this up?

 I can do an actual midi cable straight from the Linn to the Disting, but then I lose all that Nerdseq goodness.]]>

So lets start again with a new release candidate V3.01 RC4 (skipped the internal RC2 and RC3).

Here are all changes:

Audio
- refactoring of the sample and audio engine to gain some more performance
- added loop, pinpong and frame + loop/pingpong functionality for samples.
- added loop start/end/frame positions as a shortcut SHIFT+OK+Increment/Decrement
- added mapping destinations for samples (AUDI SP0-11  START/END/POS) to change the start, end or both
- added resampling screens for the samples so if a sample is too long (or manually by loading the sample with SHIFT+OK) a lower samplerate can be selected
- loading samples in a lower samplerate (allows a longer sampletime) can be selected with or without interpolation
- added 24 and 32bit PCM and float sample support, fixed some sample loading issues
- added Kill command for samples
- added play sample X on audio channel Y for I2C/Multi tracks drummatrix
- added sample OSC mode. If a sample is set to one of the loop options then it can either act like an oscillator (keeps looping) or stops when a track is stopped.
- changed sample wavefile prelisten so it stops only when SHIFT is being released instead of a toggle

Envelopes
- added additional exponential envelope responses (experimental, choose LIN/EXP with envelopetype.)
- updated retrigger behaviour with ADSR envelopes so they are more equal to a typical analogue functionality

Mapping
- fixed mapping 'add pending table ticks' will work also now with XMAP
- added mapping table destinations to fire/restart and stop tables on tracks
- Added new mapping XMAP source command: XSHT is a 1 shot multi row XMAP depending on the raising state of the former row
- Added new mapping XMAP 1Shot destination commands: Multi row XMAP depending on the raising, falling or on change of the source

General
- added a basic Scope (Setup->NerdScope) with 1 trigger (no trig, raising, falling, changing edge) and 4 channels. The input/trigger values are received though the new mapping destinations Global -> SCTV (for the trigger input), SCP1-4 (for the channel input). The 'timebase', enabled channels, trigger level and type can be changed in the scope screen.
- fixed sequencer screen possible glitches on lowest rows (EF-FE)
- added 'delete projectfile' which moves a projectfile to the backup folder
- fixed patch editing for Multi/I2C FX. Fixed create patches, added regular patch editing for I2C tracks
- fixed 'CBPB clock now 1xx' problem which caused an 'out of sync' if switching to dividers
- fixed issue that a new clock or patternorder would be activated already when pressing START to cue something instead of with the upcoming pattern
- fixed local trigger indicator in video pattern
- replaced unused Track 'pattern start position' mapping destination with 'Fire Patch' (TRCK TRKx PTCH) destination. Patch defined by former row
- fixed inconsistency with the sequencer screen use of the last edited pattern
- fixed pattern screen update if euclidean is being changed (showed accidentally on the Launchpad)
- added colours will now also be copied/pasted on the sequencer screen
- added VEX connected PC Keyboard to Midi routing which adds the full support of the midi in functions but then for the PC Keyboard (including polyphony, recording etc) (Setting in the Midi/I2C setup screen. PC Keyboard > Midi Input Port/Channel X and in the general routing you use port/channel x then to be used as track record etc just like it is a midi device).
- fixed possible wrong finetune scaling if 'avoid' was selected for local cv/gate
- updated many copy+paste parts for patterns which adds more 'compatible to each other' fields
- fixed user interface import/export which didn't save the 'Window Lines' colour properly
- fixed track and drum matrix mute and solo with the PC-Keyboard
- added uppercase functionality for all written characters (User Interface screen) 
- fixed accidentally change of the trigger type when increasing/decreasing euclidean values in the modular trigger column

MIDI
- fixed hanging MIDI scale note
- added user harmonics from MIDI keyboard (Midi Input Setup Detsination). Changes a new scale (5A/90) to the midi keyboard pressed notes.
- fixed stop of midi notes when entering the midi pattern screen via OK

Trigger16
- added a per-column destination and triggertype for the T16 drum matrix
- updated Trigger16 triggertypes to fully match the local triggers (needs Trigger16 Firmware V1.1 update)

DualChord
- fixed missing note off/gate off issue with dualchord on pattern stop
- fixed 'set dualchord trigger' command
- fixed dualchord trigger to 'other' destinations than the dualchord itself
- added random trigger types to DualChord matching the local track options
- fixed missing (not working) chord types for the 2nd dualchord part (needs Dualchord Firmware V1.3 update)

Tables
- fixed table editing for the transpose column
- fixed table bug where tables using >>> and zero selected allowed notes would cause an endless loop = freeez
- fixed table transposition with and without quantization
- fixed random table transpose (random seed issues)
- changed default for midi tables to 'no retrig' for all 16 rows

Files
- added alphabetical sort of directories (enable in setup screen)
- fixed retries when no sd card could be found
- added additional save test in case of incomplete or incorrect project saves
- added compile time as the save file time
- the save file time is now set to the compile time 

As usual, this is a release candidate. It is not intended for productive use as I can't guarantee that they are no unexpected side effects. Also saved projects will guaranteed work for the release version but are not backwards compatible to load with 3.00 or earlier. So be aware to backup your projects / SD Card first!!! (Which is something you should do anyways from time to time)
But with installing it and trying it out/testing you help getting the version ready for stable use. I aim as usual to release as soon as possible.
