MaxMSP GR-1_Controller v1.02
Q: Why does the GR-1 come without a IEC power cable?
A: This is because most people have at least a couple of these cables lying around left over from older discarded devices. It’s better for the environment.
Q: Why does the GR-1 come without a printed manual?
A: Because the manual receives significant updates every few months, and it saves the environment.
Q: How to store performance/global menu settings like midi channel, led brightness, etc?
A: See the section “Performance quick save”. Note that saving to /internal/performance 1 will restore these settings on GR-1 startup.
Q: I want to use the GR-1 as a normal sampler without granulation going on. How to do this?
A: Patch menu (Shift+Patch) -> Sample mode -> Audition.
Q: There’s just one filter? Is it then paraphonic? How to use the gr-1 as a fully polyphonic device?
A: You can use MIDI MPE devices to achieve full polyphony. You can use sampled sweeps to emulate the polysynth’s typical filter envelopes. Without MPE it indeed is somewhat paraphonic.
Q: My USB stick or drive isn’t working with the GR-1. How do I get it to work?
A: See the troubleshooting section about USB drives.
Q: My USB sound card isn’t working with the GR-1. Is it supported at all?
A: Only the so-called class compliant USB sound cards are supported. Others, especially most expensive or older cards require special driver support, and the GR-1 doesn’t have that. However, there are hundreds of class compliant USB sound cards out there. Check the list in “Supported USB sound cards” for more information.
Q: I have audio dropouts or a lowering of the density parameter. What is this, and how to avoid?
A: See the “Polyphony” chapter.
Q: The grain density seems to oscillate when there are a lot of grains (combination of high density and high grain size settings). What is this?
A: This is normal. Per voice you can “only” have 128 simultaneous grains. The grain scheduler wants to add more, but the system refuses. Then some grains reach their end, and the scheduler can add grains again. This causes an oscillation. The trick is to limit the combination of the grain size and density setting a bit, and then the density will be constant. Another way is to raise the Grain stealing threshold. Standard this is 0 (no stealing).
Q: I want to hook a GR-1 up to my DAW, how does this work?
A: There are two ways:
1. DIN MIDI: Use a USB-to-DIN MIDI adapter/sound card, and hook it up to the GR-1’s MIDI IN DIN port. This works well enough for standard MIDI controls like notes, pitch bend, and the odd CC. However, a DIN MIDI connection is not the best if you want to have a lot of smooth automations.
2. USB host-to-host interface. For instance, the iConnectivity mio2. As you may know the GR-1 has only USB A ports, and is a USB host. Your PC or Mac is also a host. There are no ways to directly make a USB connection between them. A host-to-host interface takes care of this.
Q: Sometimes, when switching to a new preset, a parameter resets itself. What is this, and how to avoid?
A: Since switching presets gives each knob a potentially different value, the actual knob position may not represent the underlying value anymore. Since the knobs are quite sensitive they may pick up the slightest movement or even noise in the system. To remedy this you can use “Setpoints” in the performance menu. That way the knobs are locked when switching presets. The lock disappears when you turn it to the actual value.
Q: I want to save separate patches and samples to internal storage. Is that possible?
A: It’s only possible to store performances to internal storage. But using a so-called “performance quick save” is actually much faster and easier than saving a separate patch. Please look it up in this manual. It is not allowed to store separate patches and samples to internal storage. The reason for this is that the internal storage is limited and there’s no delete function.
Q: I want to rename the performances in the internal storage. Is that possible?
A: Sorry, no. For this, use a USB stick with folders you have created and named yourself.
Q: In multitimbral mode, sometimes I cannot enable a specific part. What is this?
A: The GR-1 doesn’t allow the same preset to be active in multiple parts. Please make sure the other parts are assigned to other presets, and then you’ll be able to activate this part again.
Q: Windows says the firmware file contains a trojan? How can I still download the file?
A: Windows 10 (and up?) is definitely wrong about this. In the tgz archive there’s an exe file, but it’s an ARM/Linux executable, not an Intel/Windows executable. Disable Microsoft Defender and download. This is what is called a “false positive”, and you should report it to Microsoft.
