Hello my friend! Recently, Gumroad removed the feature of receiving payments through PayPal, and currently only allows Stripe or bank accounts for receiving payments. As a Chinese individual, neither of these options are viable, so I am unable to receive the money earned from sales into my personal account. Gumroad doesn't seem to prioritize this issue, hence I have decided to switch to selling my work on Patreon. Please visit patreon.com/DarlingLee to purchase my work or subscribe. I will resume using Gumroad for sales once they provide viable payment methods for us Chinese users. Thank you for your support.

您好我的朋友！前段时间Gumroad撤销了使用paypal左右收款账户的功能，目前只能使用Stripe或者银行账户作为收款方式，作为中国人，这两种方式都无法使用，因此销售所得的金钱都不能收款到我的个人财产中。Gumroad似乎对这个问题并不重视，因此我已经尝试转到Patreon中销售我的作品。请前往 patreon.com/DarlingLee 购买我的作品或进行订阅。待Gumroad重新为我们中国人提供可用的收款方式后再重新使用Gumroad进行销售，谢谢您的支持。

This is a set of MIDI signal sending and receiving tools(M4L Device). You can freely send MIDI signals from one track to any other track in an Ableton Live project.

1. It provides 12 optional channels (I don't mean MIDI channels, but channels for sending and receiving), so you can send up to 12 different sets of MIDI signals in one Ableton Live project for receiving.

2. You can freely choose to receive all or part of MIDI signals, including note signal, CC controller signal, Poly signal, Program Change signal, post-touch signal and bending wheel signal.

3. You can raise or lower the received signal by up to 5 octaves (4 full octaves and a group of 12 semitones).

4. At the receiving end, you can choose whether to enable the MIDI signal of the track where the receiving end is located to work.

You may use them in the following situations:

1. When you need to play the same notes on multiple tracks, you don't need to copy and paste the midi clip to other tracks to hear the effect of playing at the same time in real time;

2 When you use the same CC controller or bending wheel and other information control on multiple tracks, you do not need to edit the CC controller or bending wheel and other information on each track, but just edit one track to hear the effect of multiple tracks being controlled in real time;

3. When you need to play a set of chords or melodies on multiple tracks, but need to play at different pitches (such as different octaves), you no longer need to copy and paste midi clips and perform transposition operation to hear the performance effect in real time.

2023.2.28 update log:

1.Now this device got a new name:MIDI Wormhole;

2.Now you can set a reception range for midi note reception（only thke effect when the "note"button is on);

3.Now you can choose to exclude some controllers when selecting to receive cc controller signals(only thke effect when the "CC"button is on)；

4.The sender and receiver are no longer separated, that is, you can choose to use as a sender or receiver in one device;

5.Now you can configure up to 128 signal transmission channels in one ableton live project.

这是一套MIDI信号发送和接收的工具(M4L插件），您可以在一个Ableton Live工程内自由发送某个轨道的MIDI信息到任意其他轨道。

1.提供了12个可选通道（我意思不是说MIDI通道，是发送和接收的通道），所以您可以最多在一个Ableton Live工程发送12组不同的MIDI信号以供接收。

2.您可以自由选择接收全部或部分的MIDI信号，包括音符信号，CC控制器信号，Poly信号，Program Change信号，触后信号以及弯音轮信号。

3.您可以对接收到的信号进行最多5个八度的升高或降低处理（4个完整八度和一组12个半音）。

4.您可以在接收端选择是否启用接收端所在轨道的MIDI信号进行工作。

您可能在以下情境中使用到它们：

1.当你在多个轨道上使用同样的音符进行演奏的时候，您并不需要进行复制和粘贴等操作就可以实时听到同时演奏的效果；

2当你在多个轨道上使用同样的CC控制器或者是弯音轮等信息控制的时候，您并不需要在每个轨道上进行CC控制器或者弯音轮等信息的编辑，而是只需要编辑一条轨道的信息，即可实时地听到多条轨道同时被控制的效果；

3.当你需要在多条轨道上同时演奏一套和声或者旋律，但是需要在不同的音高（例如不同的八度上）进行演奏时，您不再需要复制粘贴midi剪辑并进行移调操作即可实时听到演奏效果。

2023.2.28更新日志：

1.现在开始，设备已更换一个新的名字:MIDI虫洞；

2.现在您可以选择接收的midi音符范围(仅当“音符”按钮点亮时生效）；

3.现在你可以设定接收CC控制器时排除某些控制器不进行接收(仅当“CC”按钮点亮时生效）；

4.发送器和接收器已经整合在一个设备里面，也就是说，您可以选择此设备作为发送器或者接收器使用；

5.现在您可以在一个Ableton Live工程里最多可以配置高达128条传输通道。

1.1 Update Log:

Modified the "send" and "receive" animations;

Added an "MPE" switch to enable the device to support MPE signal transmission;

Added the function of controlling the delay of received MIDI signals in milliseconds(0ms-10000ms).（There is a bug）

1.1更新日志：

1.修改“发送”和“接收”动画；

2.增加“MPE”开关以使装置能支持传输MPE信号；

3.增加对接收到的midi信号进行以毫秒为单位的延迟控制的功能（0ms-10000ms）。(存在bug）

1.2 Update log:

1.Added a MIDI output monitoring section to monitor the MIDI messages sent out, including note, aftertouch, program change, modulation wheel, pitch bend, sustain pedal, and other CC messages.

2.Added a synchronization feature to the control area that delays the output of received MIDI messages by a specified number of milliseconds or note durations.（There is a bug）

3.Optimized several bugs, such as the issue where the device had to be manually selected with a channel number after being inserted into a track to function properly.

4.Modified the user interface.

1.2更新日志：

1.增加了midi输出监视板块，可以监视MIDI输出的信息。包括音符，触后，Pogramchange，调制轮，弯音轮，延音踏板以及其他CC信息；

2.在控制把接收到的midi信号延迟输出的区域增加了同步功能，您可以根据毫秒数或者音符时值来调节将接收到的midi信息延迟输出时间；(存在bug)

3.优化了若干bug，例如把设备插入轨道之后，必须手动选择一遍通道编号才能起作用的问题；

4.修改了UI。

2023-07-11 update:

The MIDI delay function has a bug where occasional note release signal loss may occur when the delay function is added, causing notes to occasionally not release properly. A fix has not yet been found, and the function has been temporarily removed. It will be added back in when a solution is found and a new version is released.

2023-07-11更新：

MIDI延迟功能存在bug当加入延迟功能后，偶发性出现音符释放信号读取不到的情况，使得音符偶发性不能正常释放）。暂未找到修复办法，暂时去除了这个功能。待找到修复方法后再重新加入以新版本发布更新。
