Physical Music Interface

Midterm Presentation

The idea

• Handheld mic looper station
• Modular lap station

○ Trigger + fader station

+

Handheld Loopstation

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

Handheld Loopstation

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 recording 4. User must be able to play a loop without recording NTH: 1. Save audio 2. Connect to another person's loop station 3. Sound FX

Alternative A

Current 3 input design:

• ‘a’- start rec
• ‘s’-set loop/rec
• ‘d’- play loop/mute rec

DEMO

SIMPLE USER TEST

• Not very intuitive for

non-experienced users

• Takes about 5 mins to understand
• The visual feedback for the

device cuts learning time down significantly

• Is there a way to convey this

non-visually?

Alternative B

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

Alternative B

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 ○ … etc

• Button2

○ Stop everything

Handheld loop station

Questions / Concerns:

• Instead of having unlimited number of overdubs
• nly limit it to four because that would match

slider channels ○ 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 this version

• Which workflow could be better between

Alternative A and Alternative B?

Lap Station

1. Lo fi prototype

Trigger pads Record button Power switch Scrolling wheel

Recording and playing

Faders Prototype

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

Lap Station

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 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

• ption of splitting them up?
• Is it necessary to have students be

able to rec their own sounds into the pads?

• Any suggestions?

Feedback

• 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

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?
