It's alive!!!! #Turbowave #CommanderX16

Look what arrived! 1st prototype for the TurboWave X1688! Being the first prototype I don't have high expectations. Even if it doesn't work, I still made great progress on WaveBoy today. Here's hoping at least parts of this card work though! #TurboWave #Prototype #Chiptune #CommanderX16

Teaser for what the initial UI looks like for generating waves. This feature applies the manipulator across all 16 waves of the current patch changing 2 parameters over time. #WaveBoy #Eurorack #Module #Chiptune #Lofi #Wavetable

We hope everyone had a lovely🎄! WaveBoy 0.65 was our big thing for the Holiday but am happy to report I have finally started work on the Generators feature! For now we hope folks get to enjoy time with friends, family, and synths! #WaveBoy #HappyHolidays

Having a little fun with 2 WaveBoys (both running 0.56 of course!) All sounds made just with these 2 WBs. Left is oscillator (with CV modulation and internal volume env). Right is realtime delay. #Delay #WaveBoy #Eurorack #Modular

WaveBoy 0.65 firmware is finally out! * Superior Pitch Tracking * New Integer volume mode * Improved alt audio modes * Internal speed improvements LOTS of internal changes. There may be bugs but overall it's an awesome update. #WaveBoy #Chiptune #Modular #Eurorack #Lofi #GameBoy

Well...no 0.56 tonight. I had everything done but had the git merge explode into an absolute pile of garbage and made it worse when trying to fix it. So I need to pick up those pieces, retest and manually revert some things. Some days I just really. really. REALLY. dislike git. *sigh*

I had a bit of a false start with a few oops bugs but 0.65 should be coming very soon! Hoping to get it out by sometime today. Folks that placed a recent order will get 0.65. Folks with existing WBs will have to retune their WBs but it's easy to do (I made a video for it too). #WaveBoy

Working on a how-to tune the WB video today! Means firmware 0.65 is nigh! Production value isn't stellar but I used a lapel mic this time at least! #WaveBoy #Tuning #Eurorack #Modular #Chiptune #VideoEditing

Sneak peak at the new tuning process instructions. It takes maybe 5 minutes and no longer requires a tuner. Hoping to make a video on the process tomorrow to include with the documentation. The next FW release is around the corner! #WaveBoy #AutoTune #Chiptune #Modular #Eurorack

Turbowave X1688 prototype cards ordered! Holy cow tariffs really suck! Much worse than when I ordered the first production WaveBoys. Yikes.

With all the TurboWave work I've been doing, I've been jamming out to some sweet TG16 music since that should be roughly what TW will sound like. Soldier Blade is the best TG16/PCE video game soundtrack, change my mind! vgmrips.net/packs/pack/s... #TG16 #SoldierBlade #MusicSky #VGM

Alt audio modes seem to work much better in 0.65. It's like a new module! Downside? 0.65 will require V/Oct re-calibration. No way around it :/ But it's both easy and fast to do. More testing required but I'm sooo happy with the results so far! #WaveBoy #Eurorack #Modular

It works! And I finally found the root cause. My new (and vastly simpler) tuning solution exposed it. Had to do with an inefficient way of updating timer values in the audio timer which would slowly cause drift at higher pitches. It's been a hidden cause of pain for years, oof! #WaveBoy #Modular

I really hope this ends up working because it's soooo much simpler! It's nearly automatic! #WaveBoy #Tuning #Chiptune #Modular

I think WaveBoy 0.64 may be feature complete! Basically DMA and a new integer volume mode. Stopping there because in 0.65 I may want to take yet another crack at improving tracking, again taking some ideas from TurboWave (pre-computing timer values). #WaveBoy #Eurorack #Chiptune

Even though I'm writing TurboWave stuff lately, WaveBoy is benefiting. I finally figured out an efficient integer based way to handle volume attenuation (using fixed-point arithmetic and scaling). That's going onto 0.64 firmware along with the DMA stuffs. #WaveBoy #Eurorack #Chiptune

TurboWave firmware actually outputting stuff to pins! I'm trying to test things as best as I can before I order the PCBs just in case. This is the one of the DAC output pins and it's working as expected. #TurboWave #Oscillioscope

It's finally here! Chipsurf Pipeline is now available on Compact Disc both on Bandcamp and on our website! Both include a digital download of the album, though we hope folks will take the actual CD for a spin! #ChipsurfPipeline #CompactDisc #CD #Chiptune #GameBoy #NES #8bit #Surf #MusicSky

This has been a bit of my side-quest for the band and I'm VERY excited!!!

First routed prototype card for the TurboWave series! This is for the Commander X16. Includes MIDI (to the Pico) for developing the MIDI version as well. 8-bit/voice of cyclic wavetable goodness! Hope to order this as early as this week! #WaveBoy #TurboWave #Chiptune #CommanderX16 #8bit

WaveBoy Firmware 0.63 is now out! Get it here: waveboy.bitbybitsynths.com/firmware/ See our blog for all the changes with more to come in 0.64 (e.g. DMA, which I teased earlier today). #WaveBoy #Firmware #Chiptune #Eurorack #Modular

3 days of work but I now have a test branch using DMA to output to the DACs for WaveBoy! It doesn't fix the problem I hoped it would, but I think I know better what that problem is. Also needs work before I can add it to mainline. But opens up some possibilities! #WaveBoy

Upcoming firmware for #WaveBoy is really shaping up to be pretty significant. I've been really trying to improve the pitch tracking for the Sampler and this, in turn, caused me to find some other issues. Lots of datasheets and rabbit holes later, it's not perfect but noticeably improved.

My band spending some time with WaveBoys and tape loops this afternoon!

Just a tease at a potential future product. I get asked about a multi-voice version of the WaveBoy, and so... turbowave.bitbybitsynths.com #WatchThisSpace #TurboWave88 #Chiptune #Wavetable

Rest in peace, Arduino. What a beautiful ride it has been. blog.adafruit.com/2025/11/21/t...

Another feature for WB firmware 0.63 - vastly improved tuning/tracking for the Sampler! I spent a lot of time optimizing the timer interrupts for handling higher sampling rates. #WaveBoy #Sampler #Eurorack #Modular #Chiptune #Lofi

New single out from my band!

Testing out a new AC transformer on my own custom linear PSU for my rack (made up of 3 of our X84 cases). So far, so good! Linear regulators are much happier (cooler) with the new setup. Also moving some modules around. #Eurorack #Modular #ModularSynth

Skiffy 442T with the new PSU mounted all nice. This is for my band-mate but is a good test for how well the PSU fits. Only issue is the caps had to get moved a little to clear the corner tabs. Otherwise I'm happy with it! #Eurorack #EurorackPSU #Skiffy442I #SkiffyPower

Mock up of what the Skiffy 442 would be like with the new linear PSU option. I still need to do some QC on checking for ripple and noise but the burn in test went well. #Eurorack #EurorackPower #LinearPSU

Here's the PSU powering an actual module (our WaveBoy of course)! I tested it with a full 8 too! #Eurorack #PowerSupply #EurorackPower #LinearPowerSupply

It didn't blow up! Initial test of my linear half-wave rectified Eurorack PSU seem good! #Eurorack #EurorackPower #LinearPSU #Modular #ModularSynthesizer

Looking at the next project after our PSU and was looking at a I/O solution using balun line drivers/receivers. Here's my first pass. 2HP Eurorack I/O panel for the front. 4HP panel (for cases like ours that have rear slots) for the line-level I/O. #Eurorack #Modular #Balun #LineDrivers #KiCAD

The Skiffy 656 is now available! It is a 2-row (6U) 56-HP (112HP total) face-up case, like our Skiffy 642 though it has enough width for up to two rear mounted 4HP modules! #Skiffy #Skiffy656 #Eurorack #EurorackCase #Modular #ModularCase #Synthesizers #LaserCut

Assembling the first Skiffy 656 prototype! #Eurorack #EurorackCase #Skiffy #Skiffy656

Preview of the new routing stuff in 0.63! Envelope and LFO can be used to automate the wave frames and the audio output. The other WB is running the realtime delay setup as a send via a mult and Veils. #WaveBoy #Automation #Modular #Eurorack #Chiptune #Envelope #LFO #DirtySaw

Also I know a lot of folks have been waiting patiently for this, but the Skiffy 656 design is nearly complete! Of note, it can support up to 2 4HP rear modules instead of one! #Skiffy656 #Skiffy #Eurorack #Modular #EurorackCase

With 0.62 released, I'm not focusing on something WaveBoy should have had by now - the ability to use the LFO or Envelope to automate the wave-frames. Hoping to have this in 0.63. #WaveBoy #Firmware #Chiptune #Envelopes #LFO #Eurorack #Modular

WaveBoy 0.62 firmware is now available! Save-state bugfixes and a new wave manipulator are what's for dinner! www.bitbybitsynths.com/2025/10/wave... #WaveBoy #Firmware #Eurorack #Modular #Synthesizer #Chiptune

Playing around with dual WaveBoys. 1st is my DirtySaws in detune with an AD envelope in retro mode. Output is split for a pure dry output mixed with the 2nd WB, which is in delay mode. No filter. Sounds cool but I was also testing an alt recording setup and that didn't quite work out. #WaveBoy

Here's the first pass at the actual PCB design for the possible internal linear Eurorack Skiffy PSU! #Skiffy #Eurorack #EurorackCases #EurorackPower

You'll have to school me on what the Deep is in this context :) I hope that's a good thing although it is October so I guess spooky is also very much on the table.

I just wrote a blog post about a possible PSU that can be built as a kit to accompany our Eurorack cases for those that fancy a nice Sunday read. www.bitbybitsynths.com/2025/10/skif... #Eurorack #Modular #Power #Skiffy
