Physical Music Interface Midterm Presentation Handheld mic looper - PowerPoint PPT Presentation

Physical Music Interface Midterm Presentation

● Handheld mic looper station ● Modular lap station ○ Trigger + fader station The idea +

Our Process: 1. Define logic, number of Inputs/outputs Handheld 2. Design controller 3. Prototype alternatives, ensure it Loopstation can interface with lap controller 4. Test 5. Iterate and refine to single design

User Tasks: 1. User must be able to start recording audio 2. User must be able to stop recording their vocals 3. User must be able to overdub on a Handheld recording 4. User must be able to play a loop Loopstation without recording NTH: 1. Save audio 2. Connect to another person's loop station 3. Sound FX

Current 3 input design: Alternative A ● ‘a’- start rec ● ‘s’-set loop/rec ● ‘d’- play loop/mute rec

DEMO

- Not very intuitive for non-experienced users - Takes about 5 mins to understand SIMPLE USER - The visual feedback for the device cuts learning time down TEST significantly - Is there a way to convey this non-visually?

For this alternative, we got inspired by the Loopa mic, which is a microphone with a built-in audio looper and recorder. Alternative Loopa Mic B Loopa Mic 2

The Workflow of the microphone could be interesting for our project because is based on 2 inputs. ● Button1 ○ 1st press: start ○ 2nd press: set loop/play ○ 3rd press: overdub ○ 4th press: same as 2nd press ○ 5th press: same as 3rd press Alternative B ○ … etc ● Button2 ○ Stop everything

Questions / Concerns: ● Instead of having unlimited number of overdubs only limit it to four because that would match slider channels Handheld loop ○ Is a limit of 4 okay? ● Will need to be connected to a laptop with software running, so can’t be used at home in station this version ● Which workflow could be better between Alternative A and Alternative B?

1. Lo fi prototype Lap Station

Power switch Trigger pads Record button Scrolling wheel

Recording and playing

Faders Prototype Magnet connector to Magnet another Slider (each one connector module will have a different texture)

User tasks: 1. User can trigger 4 inputs that all feel different to the touch 2. User can slide 4 faders that all have corresponding pads (are made of same material) 3. User can change sounds (beatrockers sound bank) on triggers by scrolling on 2 buttons on the side of the interface Lap Station 4. User can input 4 recorded loops into each fader channel and adjust their volumes NTH: ● Student can record their own sounds into the pads

● Should we just connect both together? Or is it better to have the option of splitting them up? ? ● Is it necessary to have students be able to rec their own sounds into the pads? ● Any suggestions?

● Button: shape, size, material ● Button spectrum - where they are, where to go ● Vibrations on the mic to indicate it’s recording ● Fixed tempo? ● Tactile metronome on (or not on) the loop station ● How to indicate recording mode(the hidden state)? Maybe try Feedback a non-discrete method (not toggle record/stop but use press/release) ● Lap based: size, adjustable ● Find the fun thing from looper ● How are we going to build it? Don’t only focus on hardware. Software is equally important. ● Combine with screen based interface? Act as a teaching tool, a browsing tutorial for ours?
