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! 🙂

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 😉

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!

GR-1 Firmware 1.4.2

Dear GR-1 users,

Today we’ve released GR-1 firmware version 1.4.2. This is primarily a bugfix release.

New features:
* 6 dB output boost

– buffer wrap crackle fixed
– power/cpu usage lowered
– resonance storage bug fixed
– grain window crackles minimized
– internal root directory accessible again when loading performances
– sub-osc balance crackles fixed
– density interfering with grain clock sync fixed

Download the firmware and the latest manual from our GR-1 Downloads page.

In other news, it’s now possible to share your patches and performances to this same page! If you choose to upload, we’ll verify your work and will put it up for download, with due credit, of course.

Firmware 1.5 is scheduled for September. Beta testers are always welcome. Mail us at

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: 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! 🙂

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.

ST4 pre-final photoshoot

With the first batch of ST4 casings in production, we had time to make a photoshoot of the current, pre-final, model. As you can see, it’s easy to remove the lid and keep it opened up for maintenance.. Almost like a car 😉

The first batch is expected to be delivered to us mid November..

ST4 sample casing 2, New Sawbench

This week the new ST4 sample casing arrived. No silk screen yet, but at least everything fits. Yes, this baby is rackmountable too! So, that takes care of the mechanical bits. Everything is as sturdy and tight as it gets.

Rackmounted ST4

Now the only thing left to do are the silk screens. The designs have been finished a long time ago. We’re ordering 10 pieces to inspect the quality. If it suffices, the first ST4’s will be shipped out early November! If not, then it will be late November/early December. In the mean time we got very little to do on the firmware. From time to time we test it and make some songs.

New Sawbench: the new hardware revision is in. This means they are stocked once again: prebuilt, kit. This has built-in protection against reverse polarity (yes, those nasty guitar pedal supplies!). This is done with a miniature fuse. More details to follow.

Sawbench firmware v1.2 has been released. This makes the Sawbench, well, everything it should have been in the first place. 😉

– Tolerant to MIDI clock packets. This is quite a big deal since many MIDI devices send these.. also inadvertently.

New Features:
– Really short attacks and releases are now possible. Just a lot better for everything staccato (can you say acid?).
– Exponential envelope mode. Can be switched with CC 94. Allows for really long attacks and releases.
