I'm actually really excited to see if I can come up with something. Time-stretching, reversing or pitching up bass parts is how I often make melodies, so this will be a whole different mindset. Might have to play with some more midi tools alongside the keyboard.
Copy/paste midi clips is of course just fine. You can always transpose midi!

OSC is a whole new ballgame. It does focus you on sound design with the synth of the month, composition and mix/mastering. All with certain restrictions.

Basically the notion is to allow the "sound of the synth" to shine through, and not be modified by external modulation so as to be unrecognisable. So hence the ban on the use of chorus, phaser etc.
But note well, if the synth has built in FX such as a phaser or distortion, then you can use that and destroy the sound as much as you wish!

Hope that makes even more sense :-)

Hi,

First time participating in this very nice challenge.
As Flechtwerk is a VST adaptation of an Eurorack module, I tried to keep the Eurorack spirit and played quite a bit with parameters modulation. I also used Cardinal (an open source and free version of VCV Rack - Eurorack emulation) for the effects.

For the technical details :

DAW : Tracktion Waveform Pro 13.5
22 Flechtwerk instances
Lead
1 Flechtwerk + CardinalFx VST3 (saturation + compression) + Tracktion EQ
Plucks
2 Flechtwerk + Kilohearts Compressor + Tracktion EQ
PADS
2 Flechtwerk + CardinalFx VST3 (Reverb) + Duck + Tracktion EQ
Kick + Bass
5 Flechtwerk + Tracktion EQ + Duck
Snares + Clap
3 Flechtwerk + Tracktion EQ + Tracktion Plate Reverb
Cymbals
6 Flechtwerk + Tracktion EQ + Plate Reverb
Effects
3 Flechtwerk + Tracktion EQ
AUX SEND BUSES
- CardinalFx - Slap Delay
- CardinalFx - Long Delay
- CardinalFx - Long Reverb (Plateau)
MASTER
bx_cleansweep + bx_masterdesk classic + sonible SmartLimit

Edit : track update (pads were too low)

Hello, it's been a while! I've been trying to get into making old school drum and bass and wanted to experiment with synthesizing drum breaks. I took the opportunity to return to the OSC while doing so for fun and feedback.

Here's my submission:
https://soundcloud.com/wobbleblast/fleeting-cadenza

A considerably important inspiration for this track has been Rhythm Factor by In Deep so you should check it out too!

I found the synth rather limiting with it being mono and having only a single envelope with no attack stage for everything. So I took advantage of Bitwig's tools to the fullest in order to have more modulation and voices without it being too much of a pain. So here I'm using its envelopes to modulate volume and synth parameters, and using the Instrument Selector with multiple instances to simulate a polyphonic device.

If I counted right, I used 26 patches with many of them duplicated over a total of 52 instances of Flechtwerk for polyphony and smoother note transition. The only non-stock effect I used is a single instance of TAL Reverb 4. I used stock EQ and filters on most tracks, a bit of stock reverb here and there, a bit of stock distortion on the drum FX chain, and lots of stock delays.

Dear friends, I have made some changes to my track and here's the final version:

Hi everyone! How's it going? Hope the best!
Well, I know a road where at this time a lot of toads cross to reach a pond where they lay eggs. Every year I try to warn on social media of that location to go slowly with cars and pay attention to these cute little animals.
So this is:...

When I saw Flechtwerk for the first time...: "no presets, no pitch bending, no vibrato by modulation wheel, no envelopes, no understandable synthesis...ok, it's not for me, let's run away!". But then it was fun to use it. I hope you like the song. :tu:

Thanks to the synth developer, BJ, Richard and all the community guy for listening and friendship :hail:

See you soon around here.

Ciaooo

Really impressive range of entries here - it's fascinating how differently everyone approached Flechtwerk's limitations. ZioMau's comment about running away at first resonated with me! Constraints like this often push creativity in unexpected directions.

Submission for the month.

What a terrible synth... I don't understand the reason for its existence. No modulation options, crappy UI, bugged (even crashing my DAW a few times).... I only gave it a few hours, just to have something to submit.

Produced in Cakewalk. 12 instances of Flechtwerk. Magic7, LFX-1310, OTT, W1 Limiter as the external FX.
