GR-1 production update // The old ‘bench & something new

Dear all,

Just a post to inform you of what’s going on in the world of Tasty Chips.

First of all, the GR-1 production schedule. We’ve been on time for the last 5 months. We’re still good, but we’re 1 week behind now. We’ve identified some of the slowdowns in the assembly&test program, and solved them. We should be able to produce unhindered for the rest of the year at least.

We’ve open sourced the old Sawbench hardware! Since it was always a DIY project, a schematic is welcome. We’re still selling the DIY kits, if you’d like to try. In a way this is our thank you to the open source community that fed us, and helped us to grow. Sawbench github is the place to visit of your DIYing this or perhaps making a clone.

One more thing: feel free to visit our forum to ask for help with these. Just know that we ourselves cannot supply information indefinitely to people wanting to clone parts of it. We have a business to run. Which brings us to our next topic:

Innovation! We’re producing a new Eurorack module. It’s the first of its kind: A true-stereo convolution reverb with display. On the photo you can see a prototype, of course based on the Raspberry Pi (although we may switch to another Single Board Computer later on).

ECR-1 prototype: the first Eurorack convolution reverb!

Some features:

  • Load your own responses from USB stick
  • RECORD your own responses from the inputs, and SAVE to USB stick
  • Up to 40s impulse response
  • 128×128 full color display
    • up to 4 responses
    • envelope shape
    • parameter read-out
    • WAV name
  • Separate Dry and Wet controls
  • Attack and Release controls
  • Input gain control
  • Stereowidth control
  • Predelay control
  • Audition feature to replay your responses

The software is about 90% finished. The hardware does still need a bit of work, but prototype on the photo does actually record and replay at HIFI 48 kHz quality.

Release date: March 2019, price TBA.

ST4 September update, DIY kits

Just to keep you informed, another ST4 progress update. In the last weeks we’ve tested the sample casing and we’ve requested another one. Two PCB’s didn’t fit correctly, the other 7 did just fine. This will take until early October.

In the meantime all the presets have been added, the DIY manual has been updated with better tables, and we’re ironing out all the firmware bugs. ..And.. we’re finally compiling all the DIY kits. Still, that’s not too much work. The casing is the only real work that’s left. We strive for November, but the planning is now in the hands of the casing factory.. At least you’ll be getting your gear when you spend most of your time indoors. It makes sense 😉

In the meantime we did a minor Sawbench hardware revision (to protect against wrong AC/DC converters) and we’re looking forward to test the 1.2 firmware with its improved VCA/VCF envelopes and improved MIDI support.

When the final casings arrive we’ll start shipping out the kits ASAP! This is done in first-come-first-served order:

1. Kickstarter DIY backers first to last
2. Kickstarter assembled version backers first to last
3. Pre-order list DIY first to last
4. Pre-order list assembled version backers first to last

Today we’ll send out a questionnaire to ask you guys which version you want: rackmount or desktop.. and to ask you for your postal address.

ST4 Production

In recent weeks the ST4 electronics production has kicked off. Many of the simpler boards have now been produced and are ready to be built into the ST4 units. These were handmade right here at Tasty Chips labs in The Netherlands, just like the Sawbench synth was.

The more complex boards (exp, vcf, vca) are being assembled by machine in a fab nearby and should be done by the end of the month. Concerning the manual labor, we still have to do the voice and the mod boards. The DIY manual has also seen some major progress and many of the board pages are supplied with photos of all the soldering steps: ST4 DIY resource. More and more detailed information will appear on this DIY resource in the coming weeks.

In parallel, the firmware is still being worked on. Some news:
– Poly mode now works fine and is intelligent enough to allow 3 finger chords + solo.
– The ST4 tracker can now send MIDI out clock signals.
– The ST4 tracker accepts MIDI clock input (preliminary).
– Samples can now be tuned.
– Sample looping can be turned on or off individually per instrument.

The casing (graphic) design is ongoing. We’ve got an excellent graphics artist on board to help us with the silkscreens. The details of the fabrication are being negotiated at the moment.

Last but not least. We’ve had multiple requests whether the ST4 will become available to the public after Kickstarter. The answer is YES! Also, we are taking pre-orders. These are completely free of charge and the interested party is not obliged to buy in any way. Just send your name, postal address, and the version you want (kit, or built unit) to tastychipselectronics@gmail.com. Price for built unit will be 850 eur, 550 for the kit. Units are shipped out on a first-come-first-served basis.
