midi-data.core
MIDI data is often presented as a list of three values: [a b c].
This namespace handle's parsing of MIDI data tuples to maps that represnt there content and back.
The values [a b c] typically encode the following:
a- message type and some times a channel for that message type.b- note or paramater number for message.c- velocity or value for message.
This namespace handles parsing of these to maps in the following format:
{:midi-msg message-type ... message-type specific parsing tuple}
Examples might be:
{:midi-msg :note-on :note 60 :vel 60 :channel 1}{:midi-msg :note-off :note 60 :vel 60 :channel 1}{:midi-msg :control :number 10 :value 60 :channel 1}{:midi-msg :clock}{:midi-msg :start}{:midi-msg :stop}
Usage:
(decode [a b c])translates from MIDI data tuple to map.(encode m)translates from map back to a MIDI data tuple.
MIDI data is often presented as a list of three values: `[a b c]`.
This namespace handle's parsing of MIDI data tuples to maps that
represnt there content and back.
The values `[a b c]` typically encode the following:
- `a` - *message type* and some times a *channel* for that message type.
- `b` - *note* or *paramater number* for message.
- `c` - *velocity* or *value* for message.
This namespace handles parsing of these to maps in the following format:
`{:midi-msg message-type ... message-type specific parsing tuple}`
Examples might be:
- `{:midi-msg :note-on :note 60 :vel 60 :channel 1}`
- `{:midi-msg :note-off :note 60 :vel 60 :channel 1}`
- `{:midi-msg :control :number 10 :value 60 :channel 1}`
- `{:midi-msg :clock}`
- `{:midi-msg :start}`
- `{:midi-msg :stop}`
## Usage:
- `(decode [a b c])` translates from MIDI data tuple to map.
- `(encode m)` translates from map back to a MIDI data tuple.decodeclj/s
(decode [a b c :as data])Decodes MIDI message and transforms it to a map containing a representation of the MIDI message being sent.
Decodes MIDI message and transforms it to a map containing a representation of the MIDI message being sent.
encodeclj/s
(encode {:keys [midi-msg channel] :or {channel 0} :as m})Takes representation of MIDI event provided as a map and turns it back to
a data tuple of [a b c]
Takes representation of MIDI event provided as a map and turns it back to a data tuple of `[a b c]`
inverse-n->midi-msg-typeclj/s
Map of numbers to midi msg types. Channel numbers often need to be removed with a fn like quantize before they can be looked up using this.
Map of numbers to midi msg types. Channel numbers often need to be removed with a fn like quantize before they can be looked up using this.
midi-msg-type->msg-paramsclj/s
Maps midi message type to a to the names that b and c paramater values
represent.
Maps midi message type to a to the names that `b` and `c` paramater values represent.
midi-msg-type->nclj/s
Maps MIDI message types to the numbers used to represent them.
Maps MIDI message types to the numbers used to represent them.
n->channelclj/s
(n->channel n)Returns channel indicated by value. Typically used on first value of MIDI data tuple.
Returns channel indicated by value. Typically used on first value of MIDI data tuple.
n->midi-msg-typeclj/s
(n->midi-msg-type n)Returns key representing meaning of numerical value. If n has channel number encoded within it it is discarded.
Returns key representing meaning of numerical value. If n has channel number encoded within it it is discarded.
