Pitchbend Scaler is a very simple MIDI-only JSFX script that scales incoming Pitchbend messages by a specific factor, each channel has a different factor so it can be customized per-channel. This scaling is useful if the incoming pitchbend range is different than the range expected by the receiving synth after this script, and you can do it per-channel as well. For example a factor of 0.5 on Channel 1 will multiply all pitchbends on that channel by half, which means that the incoming pitchbend range is twice as small as the expected range (let’s say incoming pitchbend range is supposed to be ±1 semitone, while the next synth expects ±2 semitones, for example).

Despite the fact that the scale factor sliders are between 0…2, you can actually use any value outside this range, even negative values (which inverts the pitchbend but not as proper as the Pitchbend Inverter); you just have to type them manually instead of moving the slider. (which I recommend anyway for surgical precision to properly compensate for range differences)

Pitchbend Smoother is a MIDI-only JSFX script that smooths incoming Pitchbend events by slowly going from the previous value to the new value just received, with adjustable randomization and curve shape. Both the shape and the interval can be randomized as well, but only within the range you specify. When using this script, remember that it will introduce lag in the actual pitchbend effects, by its nature. That is in fact very normal for smoothing and is the whole point of it.

For instance, if you have a smooth interval of 500ms, that means it takes half a second to go from current pitchbend to the new pitchbend that was just received. Thus, the “new” pitchbend value will be in effect after half a second, and that’s the job of this script: when it sees a pitchbend event, it will smoothly go from the current value to that new one, in the interval specified. If another event happens while it is already in one interval (in other words, for that example, you send another pitchbend event before the 500ms are finished), it will instead go from whatever value it reached towards the new value, in another interval. Without this script, the “new” pitchbend value would be in effect instantly.

Pitchbend Filter by Note Channel is a simple MIDI-only JSFX script that filters the Pitchbend messages by the last Note On’s channel, while leaving all other messages intact. That is, if a Note On is encountered, it will filter out any pitchbends with a channel that does not match the channel of the note, until the next Note On is received which may change this channel. Keep in mind that even if these pitchbends may be filtered out, their values are still remembered, so that if a new Note On happens that uses another channel’s pitchbend, its value will be restored to the exact last value it had (even though it wasn’t sent before).

The main purpose of this script arised from the Key Tuner. This is because the Key Tuner splits notes on different channels with different pitchbends, so we want a way to filter out the respective pitchbends for a given note’s channel. If you have a note splitter available but cannot split the Pitchbends properly to different paths/synths, then just send the entire pitchbend bus to the different destinations, and use this script as the first thing in each of them to filter out pitchbends that are unwanted, by using the notes and their channels (that were split).

You’ll probably not find a use for this script unless you’re doing weird stuff like me, but I released it anyway, who knows maybe it is useful to you. Slightly more information on its dedicated page here.

Pitchbend Inverter is a very simple MIDI-only JSFX script that inverts the Pitchbend’s effective value: up-shifts become down-shifts of equal amount, as long as the receiving synth has an equal up/down range on both sides (which should be the most common case). It also handles the fact that negative (down) pitchbends are slightly more precise than positive (up) pitchbends (8192 values instead of 8191, because of zero), so it does the proper conversion. Please note that it inverts all pitchbend messages, on any channel. If you want only a specific channel inverted, then please route it accordingly in the host.

One use of this script would be to link the inverted result to a synth parameter that should go the opposite way of the pitchbend. For example, let’s say you have a simple sampler that does basic pitchbending by slowing down or speeding up the samples. You want to time-stretch the sample itself, without affecting its pitch, but only its speed. To do that, send the pitchbend to the sampler to have the samples play faster or slower (which also modifies their pitch), and then use a pitch shifter effect, with the amount of shift equal to the inverted pitchbend. Basically, you play the sample faster and then down-pitch it back, or play it slower and then up-pitch it back. So, you just achieved crude (and manual) time-stretching. This is just one example, feel free to use it for anything else.

Pitchbend Adder is a simple JSFX script used to add an audio signal to Pitchbend events on the channels specified. The audio signal should be “normalized” between -1 and 1, representing the pitchbend range, which gets added to the pitchbend messages already present in the MIDI bus (but also creating new pitchbend messages if needed). So be careful! You can actually get out of range quite easily (it will get capped to max/min values in such a case). Other MIDI events are passed through. The input audio signal that gets added to the Pitchbend is mono, and it is added to all the channels specified. If you use it in a stereo configuration, it will probably be the left channel, so keep it in mind.

As you can imagine, the purpose of this little script is to be able to manipulate Pitchbend from audio, while adding it on top of other Pitchbend messages already present. If there are no such messages, then it will simply create Pitchbend messages out of the audio signal (because it is added to zero), while its precision is not limited to buffer chunks (unlike ReaControlMIDI), so it is superior even if you use it only to create pitchbends out of audio signals.
