EXT IN

, the internal synthesizer in

Bitspeek

will be disabled and the external signal

will be processed by the formant filter instead. There is a built-in pre-emphasis
stage that boosts higher frequencies to prevent the result from becoming too
"muddy".

AUDIO OUT

The output signal. If you have connected both input channels

(or external input

channels)

you would normally want to connect both outputs as well.

Bitspeek

will

not automatically mix or split signals from stereo to mono or vice versa.

GATE IN

The gate input is most often used together with

NOTE IN

to control

Bitspeek

from a

CV source such as the Matrix Pattern Sequencer.

GATE IN

and

NOTE IN

works

both with

KBD MODE

disabled and enabled. When

KBD MODE

is enabled,

Bit-

speek

will only produce audio when the gate CV signal is high.

Regardless if

NOTE IN

is connected or not, the gate input can be used to force

triggering new "frames". Set

FRAME RATE

to 0 to use this feature.

NOTE IN

This CV input lets you control the pitch of the built-in synthesizer

(and also of the

NOTE and PITCH CV outputs)

. Just as with KBD MODE you normally want to turn

TRACKING

down to 0% when connecting NOTE IN.

PITCH IN

PITCH IN

is a pitch adjustment input with scalable range. Unlike

NOTE IN

, this in-

put is bipolar and it is not "quantized" to semitones. You can use it to add modula-
tion to the synthesized pitch or to hook up one

Bitspeek

to another to follow the ex-

act same pitch.

GATE OUT

This output works both as a gate signal

(to trigger other synths, etc.)

and as an en-

velope follower. The output is logarithmic with respect to the input amplitude

(unlike

the VOICE and NOISE outs, which are linear)

. In other words this output works as a

dB measurement and the range is -36 to 12 dB. When connected to the gate input
of a synth in Reason, the synth will trigger a voice when the signal raises above ap-
proximately -35.5 dB and the device will release the voice when it drops below
again.

NOTE OUT

This output will transmit the pitch of the analyzed signal. The output is scaled, offset
and quantized to the standard CV note range in Reason. This makes it easy to wire
a synth to play along with

Bitspeek

. Just connect the

GATE

and

NOTE

out to the

synth and set it to "monophonic legato" mode. Route the audio of the synth back
into

EXT IN

Bitspeek

and you have rolled your own flavor of robotic speech.
