A:1 x 1.8 x 1.4 inches (2.6 x 4.5 x 1.5 cm) and weighs approximately 0.6 ounces (18 grams.). One of our goals was to make MUGIC® as small and unintrusive as possible for performance.
Q:Can I track absolute position with MUGIC®?
A:This is a hard problem with any IMU sensor, since they only provide orientation and acceleration, not speed or position. For instance, it is physically impossible to distinguish a device traveling at constant speed from an immobile device since in both cases acceleration is zero. Using additional constraints (such as when the device is mounted on a doorframe or other physically -constrained element, or if the device undergoes a cyclical motion such as a rotation about a fixed axis) it is possible to achieve excellent positioning. For a free-form sensor like MUGIC®, it remains an active research project to estimate accurate speed and position, although in theory using physical constraints from an instrument such as a violin (if mounted on the box hand) should help. https://cdn-shop.adafruit.com/datasheets/BST_BNO055_DS000_12.pdf?fbclid=IwAR39iBXEzhbg2LK9Cv4X-RsQeHW8es390-tidt0F-jdZSAhF7Ba_Mfz5J4g
Q:How frequently is it sampled from the device / how much data does the device send?
A:The data is sampled by default every 25ms (40Hz) and sends a single UDP packet of less than 512 bytes, as a result the network traffic is minimal. The frequency can be adjusted through the loop_delay parameter, but the device maximum frequency is every 10ms (100Hz) and it is hard to configure the sensor to achieve this throughput.
Q:How long does the battery last and how long does it take to charge?
A:While on WIFI mode in full use, the battery lasts about 1hr and 20 mins. If connected to an electric outlet (or computer via USB), it takes about 20 minutes to recharge to 100%.
Q:What computer does MetaBow™ work with? (Windows, Mac, phone, Tablets)
A:Currently, MetaBow™works on both macOS and Windows computers. An app for iOS and Android phones and tablets will be released over the coming months.
Q:Can I use MUGIC® to control my other hardware and synthesizers?
A:Yes, if you have the proper tools. You will still need a computer for MUGIC™ to connect to, software to manage your data (e.g. MIDI), and an interface that has MIDI capabilities (most do). You simply need to use the “MUGIC™ to MIDI patch” (We will soon put them up on the "Downloads page").
Q:Are there composers writing for MUGIC®? Can I get in touch with them to commission a new piece?
A:Of course, please visit our “Repertoire page” to see all the pieces that have been written for and performed with MUGIC™. There you will also find contact information for composers if you are interested in speaking with them about writing for/with MUGIC™ and you may reach out to them directly to discuss new commissions. , Aside from Mari Kimura who has been writing numerous pieces for MUGIC™ and violin, renowned contemporary music composer Dai Fujikura just wrote a new work commissioned by Mari Kimura, called “Motion Notions” which is published by Ricordi. There are many more composers who have been writing for MUGIC™; please find and contact them!
Q:I am an instrumentalist and wants to perform with MetaBow™. Are there pieces and scores available?
A:Yes! Please visit the Repertoire section under the Software/Performance page where you will also find links to scores and contact information for composers who are actively writing and working with MUGIC™.
Q:Do I need to be a computer programmer or coder in order to use MetaBow™?
A:No! We have built a user-friendly suite of software and devices enabling you to use MetaBow™ directly on your phone, tablet, or computer without any coding or computer programming experience. Our patches and pedagogical software can be downloaded from the Download page. Their corresponding tutorials can be found in the About/Tutorials section. Some experience with Max will certainly help broaden your capabilities, but our patches can be used (and hacked) to achieve fairly advanced results with relative ease.
Q:So, what can I do with MetaBow™?
A:MetaBow™ has been designed to capture nuanced gestural data allowing the user to control parameters in music software (like Max and Ableton Live) or any other mapping applications (live video, lighting, Arduino projects, etc.) MetaBow™ uses OSC data and can be thus used by any software that accepts this format as an input.
Q:What is MetaBow™?
A:MetaBow™ is a bow and an enhanced interface that can be connected to our own app or any other software using Bluetooth Lowe Energy (BLE) through an open sound control (OSC) protocol. As a performer or composer, you can use it for digital sound processing (MaxMSP, Ableton Live, etc.), to develop multimodal mapping strategies (TouchDEsigner, Unity, Jitter, etc.), and more. As a violin student or pedagogue, MetaBow™ introduces a learning environment that uses real-time objective data visualizations to enhance your teaching and practising routines, translating your gestures into meaningful data.
Q:Do you have tech support?
A:We do have a team of MetaBow™ Experts, who are available to help you. Go to the MetaBow™ Forum page and share your questions with us.
