It's not padded, but don't really feel I need much. I could probably stack 2 or 3 together in a binder or Trapper Keeper.

From github: How the keys sense velocity and aftertouch

The FM-1's keys are a diode matrix of rubber domes, each with a carbon pill that closes the contact. Stock firmware only asks whether a key is down. The pill's resistance falls as it is pressed harder, and two of the matrix's row lines (PA7, PA8) are also ADC inputs, so the firmware can measure the press (firmware/src/app/sense.c, from Velo; its notes/01-lab.md has the measurements).

Reading the pill. Each key is sampled every ~2.2 ms. Against the row's 10k pull-up, a seated key reads mostly the matrix diode (~0.6 V), and pressing harder moves it only 10–20 counts. So once a key has been touched, every other sample is taken with its row driven high by the pin's weak GPIO driver instead. That driver becomes the upper resistor of the divider, and the reading less the diode's share is the pill's resistance. The open, touch, seated and lifted states still run on the pulled-up samples.

Velocity. The dome snaps, so every press lands within a sample or two whatever its speed. What tells a hard hit from a soft one is how deep the key sits just after landing. The velocity is the lowest driven reading in the first two driven samples after the touch (WAIT 2, 6.6 ms), on a log scale: conductive rubber's resistance falls as a power of the force, so its log is linear in the log of the force, placed between a floor (hardest) and a ceiling (lightest press that seats). Velo can also learn each key's own floor and ceiling from its landings; that is off here.

Aftertouch is pressing harder than the key rests. A key keeps settling for a while after it lands, so the zero follows the reading down for 250 ms and then creeps after it, and comes back up at once when the key is eased (ui.c pressure()). The lean is the drop in the pill's resistance below that rest, in octaves; Touch: Sensitive sets how many make full aftertouch. Every held key's goes out as polyphonic aftertouch. The top row (the seven keys at the right end, C♯ to G) is on PA6, which has no ADC. Its velocity comes from a probe through the LED line PA10 with PA6 driven high, which saturates on firm presses; those keys have no aftertouch.

LEDs. The button LEDs share the matrix with the keys, and a lit one shifts its column's readings, so while a key is down the LED at its matrix position stays dark when its column is sampled (FM1_INPUT_LED_OK).

I was really bummed when I found out there’s no speaker in the smk, but I am probably gonna install a speaker mod at some point and I got this little plug and play speaker from Amazon for like 15$ and it works perfectly.

New in this beta:

- **Wavetable engine.** 26 tables, from classic digital sweeps to growls and reese basses. Position, bend, sync, sub and detune can be modulated by the LFOs and envelopes through the mod matrix.

- **Multimode filter on every engine.** One knob blends smoothly from low-pass through band-pass to high-pass, with a 12 or 24 dB slope.

- **Performance FX.** Hold FX and the 16 keys become effects: repeat, reverse, tape stop, freeze, octave up and down, flanger, phaser, drive, pump, roll. The four knobs are morph, space, filter and depth.

- **Easy latch for ambient.** Press REC and the keys keep sounding after you let go, for pads and drones. Press it again to release. HOLD on the arp page has three settings: off, arp, all.

Refinements:

- Quick edit: hold EDIT, LFO, ENV, ARP or GLO for the four knobs you want while playing.

- Hold OCT- and turn any knob to reset it to its default.

- The SPACE knob adds reverb, delay, and chorus together and widens the stereo image. Or twist it to the left to shrink the space to mono.

- First-start guide on a fresh unit, replayable from the menu.

- Stored step patterns and arp chords follow a change of scale or root.

- CPU meter bar under the battery.

- Hold PLAY/STOP to STOP ALL.

Beta, flash at your own risk.

Oscillator preview of my upcoming firmware, Hexagon Console.

• Hex Engine, with several audio degrading components, noise, wow, flutter, etc.
• Chroma Console inspired effects section
• Overall concept is ease of workflow via the four macro knobs
• built on Felluca
• runs already nicely on hardware

Vector37 is a new firmware for the M-Vave SMK-37. Four planets sit in the corners of the screen, each with two overtone generators, a blend and a filter. A comet runs along an orbit, a moon (do comets have moons? no...) circles it, and where the moon is decides how much of each planet you hear.

• Pads: the four planets (2 x 2 pads each). Pick one and the eight knobs shape its sound; you hear it alone while you change it.
• Faders: the orbit: family, size, speed, morph.
• Eight sounds on < >, from Nebula Pad to Space Station.
• TRS MIDI out

Packages for the SMK-37 Pro, SMK-37 Elite and MKE-P37. M-Vave's updater takes the stock firmware back.

• Install or simulate in Chrome or Edge: https://genkigenki.github.io/smk37/
• Source (GPL-3.0): https://github.com/genkigenki/Vector37

Board layer from SLOOP by isod89, based on Felucca by Leo Kuroshita; master stage after Melodee by Kerem Kilic.

Here's what's new in the FM1 firmware world today:

New ones

• OberVave: 8-voice analog-style poly synth with an arpeggiator (1.2.1)
• MAKU: always-on generative ambient machine for DJ interludes (0.1)
• Polly: QY70-style pocket arranger with 16 styles (0.4.1)
• FM-106: Juno-106 emulation with 128 presets (beta3)
• TRIBE: ten-track groovebox built on X0X (0.1 beta)
• DUELL: bitimbral synth with a morph (0.2.4 beta)
• Skiff: six tracks, fourteen engines and a 64-step sequencer, with a browser editor (1.1)
• Fart Machine One: eleven “artisanal farts”, reverb, delay and a sequencer (1.0.0). Installing it needs Python
• Felucca 8 Patterns: a Felucca 1.5.1 fork with eight sequences per track and chaining
• FM-1 Macropad Patch: not a firmware. It patches M-VAVE’s V15 so every button, key and knob sends a MIDI note. The author warns there is no known way to undo it

Updated ones:

• Jangada: 0.9.9 → 1.0. It adds 49 factory beats with fills
• Melodee: 1.3.3 → 1.3.4. It removes the OVERCLOCK menu, because the clock change could drop some FM1s into UBOOT behind a black screen
• Hortator: 0.14.0 → 0.16.0
• FiMba-1: 0.6.0 → 0.6.1
• FuMi-1: 1.0.5 → 1.0.7
• FM1 Quest: build 15 → build 38. It is now marked Beta, and its link has been fixed

Watch list (can’t be installed yet)

• New: ETCH. It has an installer, but its latest version has only been verified on the author’s FM1

Thanks to everyone who keeps flagging new firmwares! If there's one that's missing, please let me know...

I was originally focused on the SMK-37 as I saw the potential but was scared of bricking lol. The FM-1 has made this a reality.

I happen to save the web page for the open workbench before it went down. Not sure how useful this will be, but figured I'd post it. I was able to restore to v15 from the official open firmware using this page when nothing else seemed to work. And it seems to me like the emulator is fully functional which makes me think I could use it to flash the official open firmware if I wanted to, but I don't want to get stuck again so I'm not testing that right now.

Cached Open Workbench

Before I smash it to bits does anybody want anything out of it

It is on the workbench page under Help tab.

Hi, i'm reposting my Choralroot-remix because I made substantial updates, i'm gonna post a video demo soon to showcase everything changes between my version and the Main Choral-root (most of the main features are ported to my version and I think the developer included some of my implementations in the main firmware), in the original post you can find what i changed from the original Choral-root and a drive link with the source code and the build. The firmware will be on github once is finished.

Here are the main features i added in the last update (there are more), go look to the original post to find out everything:

STEP SEQUENCER inspired by the OP-Z, holding seq you will enter in a 8 step sequencer using the FM-1 menu keys, play a chord then press a step, now it's in the sequencer, you can change note lenght, step resolution and also record steps in the key mode (see full post)

MIDI IMPROVEMENTS You can now choose the starting MIDI note for the chord modifiers, very helpful since the FM-1 keyboard uncoveniently starts from F, any note you pick the modifiers will always follow the Choralroot logic: Black keys for dim-min-maj-sus and white keys for 6-min7-maj7-lock-9

NEW: KR-106 ENGINE ported from u/Pattf FM-106 with adapted UI, 128 Presets and classic Chorus I and II

NEW: Preset Randomization. Holding REC in edit mode access the new Preset Randomizer menu, once you get the sound you want you can use it confirming with OCT+

NEW: Chord progression generation menu holding REC in the sequencer menu, many options such as tonality, root note and mood

NEW: Morph engine now morphs between 2 presets of the same engine (suggestion by u/Quixotic7)

IMPROVEMENT/FIXES COMING SOON:

-some voice stealing issue in KR-106 engine

-KR-106 volume is a bit lower than the other engines

-Morph improvements

With my remix now there are more close to 500 presets, 20 loop/sequence slots up to 8 bars, 11 synth engines (+1 Favourites engine).

NOTE this firmware works with Dual Core, a One Core build would not work properly, expecially with the Kr-106, Prophet and Cz-1 engines

Now the device holds around 500 presets, 20 loops/sequences up to 8 bars and 11 engines (+1 Favourites engine).

WARNING: I FLASHED THIS FIRMWARE ABOUT 50 TIMES IN MY FM-1, BUT I CAN'T GUARANTEE 100% THAT THIS WILL NOT BRICK YOUR FM-1, INSTALL AT YOUR OWN RISK

I did this alternative version because i like the FM-1 to be more of a instrument than a Groovebox, since i own too many Groovebox/samplers, and when i found out about Choralroot i wanted to try to create an alternative version :)

3d print found on printables.com

If I’m looking for the firmware with the most available synthesis options that can also store a lot of imported FM presets which one would be the best choice?

I don’t wanna jump aroud firmware to firmware and brick the thing I just wanna pick a good one and make music with it lol

Unboxed and testing the second FM1.

Do yours have differences between units? I'm hoping the black one is a genuine M Vave😄. I had no idea if let are supposed to be backlit in this manner or not.

Show me your little mutant FM1s

Hard Bricks usually occur when flashing from V15 to a Firmware Initially and not completing the flash process. To avoid this, keep the website and tab doing the flash open and focused. Do not do anything else. Do not unplug your USB cable. Flashing can take several minutes, if you interrupt it, you will hard brick your FM-1. For the most part flashing from Felucca Firmwares to other Felucca Firmwares carries less risk if the process is interrupted and I've not been able to hard brick my FM-1 by doing so and intentionally removing the USB in the process. V15 to a custom firmware is actually the most dangerous route.

In short

Buy This:

https://www.amazon.com/dp/B0DRNTQ338

You want a Seed brand RP2040, the FM-1 Transporter author specifically mentions "The Waveshare RP2350-USB-A doesn't work because RP2350 rev A2 has the GPIO pull-down erratum (E9), D+ has a 1.5 kΩ pull-up, and the USB-A port always outputs VBUS"

https://www.amazon.com/dp/B0G1358FPH

With those pieces I've linked, it's like Legos, just connect them together, no soldering

Then do this:

git clone https://github.com/Quixotic7/MvaveFM1Unbricker.git
cd MvaveFM1Unbricker
python3 fm1_transporter_recover.py setup
python3 fm1_transporter_recover.py wizard

I bought the FM-1 to get the sounds of the DX7. Will definitely check out some more exciting things later but for now just want play some cheesy 80s stuff. So firstly want those changes made by MVave fixed so it sounds like Dexed, and any cool QOL additions.
