New year, new manual

It’s been a while since the last news letter, but we haven’t been sitting still.

The GR-1 has received a bug fix update that should weed out the last possibility of crashes, and that fixes several use cases. We’ve dedicated ourselves to fixing as many bugs as possible in 2.4, before we add new features in 2.5. 2.4.0 was probably already the most stable version to date, and 2.4.1 improves on that.

To go along with firmware 2.4, we’ve updated the manual to v2.4.2, and added improved illustrations, updated lists of supported hardware peripherals and corrected many parts of the text.

Check out the new manual and firmware in the GR-1 downloads section.

GR-1 Decksavers are now on sale at various dealers all over the world. We don’t sell them ourselves. The first users have already purchased them. Some more photos, courtesy of Decksaver…

Next time, in all likelihood, we’ll have some news about our ECR convolver. Until then!

Decksaver and GR-1 firmware 2.4

Decksaver will offer custom made hardcovers for the GR-1 starting December. Recommended retail price is about 45 EUR, Decksaver tell us. See the photos below.

The GR-1 has just been updated with firmware 2.4. This offers the excellent stability of the previous 2.3.4 and various improvements to controls, MIDI out (via USB) so you can record knob wiggling as automations in your DAW, and the ability to use the ADSR sliders as part volumes in multitimbral. Download firmware 2.4 to your USB stick, or plug in the LAN cable to your router. Release notes for firmware 2.4 , 2.4 manual

All ECR-1’s came with firmware 1.1 since late May. This firmware boosts output level and slightly lowers the noise floor. Moreover, this is a meticulously tested firmware that eliminates instability. Users that still have 1.0 can swap their old DIMM (the module on the back of the unit) with a new one from us. The condition is that you send us back your old 1.0 DIMM. Thing is, we accidentally sent out a bunch of units with firmware 1.0 even in August. You can check your firmware by holding down Shift for 5 seconds. Contact us at

The next firmware update will be a big one, and available from our webshop next year.

Beware of scammers!

Just a short update here, next week we’ll update you on the real news.

Since last week we’ve had numerous reports of scammers offering the GR-1 for impossibly low prices. Some people have actually fallen for it!

The only places you can buy a new GR-1 are:
Us, from our webshop,
KMR Audio in the UK,
Perfect Circuit Audio in the USA,
Scheidersladen in Germany.

And it most definitely won’t sell for 100$ !

We ask, if you when you find such a scam site advertised on facebook or instagram, to please report it immediately. We’ve already done so ourselves, and reported the scam sites to the DMCA for copyright infringement.

An example of a scam site:

You have been warned. Don’t fall their nonsense and report them as soon as possible. Thanks in advance.

Production status and beta tests.

Dear all,

2020 is now well underway, and Tasty Chips is continuing its journey into sample based synthesis.

Tasty Chips new years Tompouce!

Let’s start with the bad news: The GR-1 production has been delayed by several component shortages, and hence production time is now expected to be 4 weeks. This is not all terrible: the attention diverted away from production can serve to improve the firmware. Read on!

GR-1 firmware version 2.2 is now being beta tested by both in-house testers and by a few loyal customers too. This will bring many new features and make it an even more usable instrument. We cannot reveal details at this moment, but stay tuned for a detailed instruction video coming next month!

More beta testing: The ECR-1, our Eurorack convolver, is now on its way to our beta testers. It is functionally complete, and performs terrifically. Even if it’s a very high power DSP system, the power usage and thermal performance are exemplary. Series production has already commenced, albeit it somewhat cautiously. Expect to see it in our webshop at the end of March. Feast your eyes on the first excerpt of the manual below. For a detailed specification sheet, please see the product page.

That’s it for now. Don’t stop making music and see you in the next post. Cheers! ๐Ÿ™‚

GR-1 Production and ECR-1 final prototype.

Just a quick newsletter, since we’ve been silent the last months.

GR-1 production

As you may know, the GR-1 has been on direct order since October. We initially shipped them within the week, but due to high demand the production time has now increased to two weeks. We’ll also be taking some days off between Christmas and New year. Early next year we hope to return to near-direct shipping.

ECR-1 final prototype

We’ve sorted the noise problems, added a final feature, and made a new, prettier, front plate design. We’re also optimizing the engine to have as long reverbs as possible, and perfecting the timing to overcome all possible glitches. We hope to have the first test models out with the beta testers in January. Series production should commence in February.

The overdue newsletter: featuring ECR-1, and GR-1.

It’s been a long time since we’ve written our last newsletter. We’ve not been sitting still. Hold on, this is going to be a long one!

GR-1 Dust covers

First of, a lot of GR-1 users have been asking us for custom dust covers. Initially there were no options, since for instance Decksaver supplies covers for the most popular devices, but not for the more niche and experimental devices like the GR-1. Recently, a GR-1 user showed us these covers. Nice find:

The dust cover and the GR-1.

GR-1 Production schedule update

Unfortunately, this summer was a bumpy one. We’ve had setbacks with a couple of our suppliers. Right now dozens of units are already finished and ready to go, but their knobs are still missing. They should finally arrive the coming week, after which we’ll send out finalization mails in bulk! All-in-all the preorder wait has grown from 2 to 3 months because of this. Keep an eye on for the exact time table.

ECR-1 [Eurorack convolver] Development

Our new Eurorack module is true-stereo convolution reverb, allowing you to use recorded real-life reverbs of many places like tunnels, caves, churches, basements, and resonators like bells, glasses, etc. While this is a first only in Eurorack format, it offers features to manipulate the reverbs smoothly and in real-time, which is actually a world first. It can also record responses on the spot and save them to usb stick. But we’ll not dive any further into the details here. We’ll reveal them at Dutch Modular Fest later on this month.

Of course the model we’ll show there won’t be production ready, but it’ll be functionally complete, at least. The last stages of development have now begun: we’re ironing out the bugs and trying to boost the performance (signal-to-noise ratio, power usage and temperature, max length of reverbs, etc)

GR-1 Firmware

For those of you that missed it, already a couple of months ago, firmware 2.1 was released. This brought a vastly more usable multitimbral mode. Numerous small additions and bugfixes were also added. After we’ve demonstrated the ECR-1, we’ll get back to the GR-1 firmware updates, starting with the most demanded bugfixes.

That’s about it for this newsletter. We’ll probably write the next one in two months or so. See you!

New GR-1 Sound pack, New videos, ECR-1 progress

Dear all,

We’ve not been sitting still. For our GR-1 customers we decided to make video’s: a tutorial and a new teaser for 2019. The tutorial covers some of the more in-depth features that weren’t covered before, including the new multi-timbral mode. Enjoy, and watch and learn ๐Ÿ˜‰

We also produced a brand spanking new set of patches for the GR-1, 32 to be specific. We designed these patches to show how versatile the machine really is. Anything from field recordings to samples of classic bass synthesizers are usable for many musical applications. There are very lush sounding ambient tracks and pads in there, and just as many glitchy and noisy drumtracks. You can check some excerpts from this pack on Soundcloud:

The new sound pack is completely free and ready to go from our GR-1 downloads page: GR-1 downloads.

In terms of actual product development we’ve not been sitting still. We’re still updating the GR-1 firmware every month or two. And our new Eurorack Convolution Reverb module, the ECR-1, has now reached the stage where it is actually usable by a non-developer. It has a small full-color display mounted and has all the buttons, pots and audio/CV in and outs it needs.

You can also look at the convolution reverb thread on Muff Wiggler if you like to know more. Cheers!

Summer update

It’s been a while since we did an update here. So here it goes.

First off: we’ve now shipped practically all of the GR-1 pre-orders from last year. The last of the December pre-orders are now waiting for their future owners. If you are one of these guys, and haven’t received your unit yet, please check your mail box for our “finalization” email. Inside are payment instructions and a request for your postal address. Once the parcel is sent you’ll receive a track & trace email.

Secondly, and not unimportant… Many of our users have said to be very happy with their new machines, praising the GR-1’s power and ease-of-use! Thank you guys. It’s so good to hear we have lived up to expectations and have correctly realized our vision.

You may have noticed in our schedule, that we’ve got a quiet summer. Indeed we’ve been set back a good month due to one of our suppliers moving their factory to a new address during these summer months, and another supplier suffering their own set of delays. Please rest assured that we are _totally_ committed to the GR-1 project and to improving both this synth itself, and our service. Hence, we are professionalizing and building up as many new supplier relations as we have to, in order to streamline future production. Demand for the GR-1 remains high, and we’ll be busy with fulfilment of preorders for the remainder of 2018. We’ll keep the schedule updated regularly.

In case you haven’t noticed, in the last months we’ve released several GR-1 instruction videos, and a new one today. More will be coming up, we still haven’t explained all the features of the latest 1.4 firmware..

40 casings in the house – Production continues!

After a long silence, we have some good news and some more good news.

We received 40 sets of casings from our Dutch anodization printing partner. They look absolutely splendid. See the attached picture.

40 sets of casings!


As mentioned earlier we have a production schedule up at:ยย Please watch this space for any updates on the production and shipping process. As can be seen on that page, we have just shipped out some more Kickstarter units, and will now go on to send out the remaining ones. This will take up to half May. Then, all Kickstarter rewards will be done! ๐Ÿ™‚

Casings and the assembled electronics ready to built in.

We’ve also not been sitting still in terms of firmware. Today we’re releasing v1.2.2, which is a bugfix release : But more importantly: v1.3 is coming up!

Version 1.3 features

  • Full support for MIDI Polyphonic Expression (MPE), including mapping of MPE Timbre and aftertouch to the MOD matrix. In practice that means support for controllers like Roli Seabord, Haken Continuum, and the LinnStrument.
  • Record position slider movement to LFO waves.
  • Numerical display for all parameters.
  • LFO DIV/MUL on knobs when synced to MIDI clock.
  • MIDI clock -> density sync.
  • Resampling loaded samples to native 44.1 (can be turned on and off).
  • Shift+Sides, Shift+Curve sliders controls loop start, end.
  • Save path remembered separately per type (sample, patch, performance).
  • LFO -> Delay time sync.
  • Custom scales for voice sliders.

Version 1.3 bugfixes

  • Filter instability solved. (happened at high cutoffs)
  • Pressing shift caused pitch changes when playing MIDI notes.
  • Better note hold.
  • Sub-oscillator crackles fixed.

We’ll be at superbooth 2018, Berlin in two weeks. There we’ll demonstrate the 1.3 beta, along with a Roli Seaboard. After this we’re open for beta testing. Drop us a line at and we’ll send you the beta upgrade.
