Т.к. планирую эту идею развивать (возможно в виде новых скриптов), создам топик. Скрипт достаточно навороченный для моего текущего уровня, но вроде все получилось :) Итак - объединение нескольких треков или каналов в мультиканальную вав. С помощью рендера. В том числе - можно из двух моно сложить стерео, но т.к. принцип посылов (на которых собственно и построен скрипт) выглядит как 1 на 1 канал, 1 на 2 канал, то, соответственно, это будет то же самое, что выставить панорамники 100R и 100L в моно-паре. Скрипты рендерят сигнал постфейдерно (пост ФХ), но и вынимают его из инсерт-треков, то есть все ваши посылы не будут рендерятся! Для этого у меня есть другой свой скрипт - "Mixdown selection".
Данный скрипт отобразит в окне ввода столько треков, сколько выделено. Ограничение 16 шт на уровне API. Также он отобразит название треков - если оно более 16 символов, сократит название по центру, а если имени у трека нет, напишет "Track untitled" с порядковым номером.
Ставим напротив трека 1 - значит моно, 2 - значит стерео. Другие данные скрипт не принимает. Если выбрать для трека моно, но у него стерео источник, то просто возьмется первый левый канал. Скрипт учитывает TS если он есть (если нет - рендерит весь трек). Ошибки буду исправлять, если что, с виду исправно. Последнее, что сейчас добавлю - скрипт использует одну функцию от SWS API, так что без SWS никак
В общем-то и все! Гифку и сам скрипт прикреплю в виде файла и исходного кода.

@Antonio, для любой ситуации, если понадобится создать многоканальную вав :) Ну или стерео.
Просто рипер отлично умеет распаковывать, поэтому логично, если бы точно также работало, но обратно.

Тестирую щас новый вариант, который складывает любое кол-во каналов с одного трека. То есть, например, можно 4 канальный + 4 канальный + 6 канальный. Но до 64 каналов в сумме. Завтра выложу скорее всего
 
Вот новый вариант - теперь можно вводить любое кол-во каналов на дорожку, однако в сумме не более 64. Данная версия по сути лучше первой и может сложить, к примеру, 4 канала с одного трека + стерео канал с другого и т.п. Кол-во дорожек все также ограничено 16 штуками. Выложу просто код, кому нужно, скопирует.
