AKAI MPC 1000 序列文件命令行实用程序

我经常使用 MPC 1000 作为播放器，在练习音乐或只是想快速演奏一些东西时支持曲目或鼓循环。我通常在我选择的 DAW 中创建一个鼓循环，然后以不同的速度导出几个 wav 文件。然后，我会将这些文件复制到我的 MPC 上，并为每个 wav 文件保存一个序列。下次我想要练习或即兴演奏时，我只需快速加载一个包含序列和 wav 文件的文件夹，并且可以轻松地在几种速度之间切换。

在 MPC 本身上创建所有序列是一项非常繁琐的任务，这就是我编写此工具的原因。我现在只需在 MPC 上创建一个“模板序列”，将其复制到计算机上，然后从中创建多个（重命名的）文件。然后，我让该工具帮助我显示序列文件的元信息并执行重复性任务，例如替换音频轨道中的文件名或替换序列 BPM。

虽然我是为从运行 JJOS 的 MPC 1000 创建的序列文件编写的，但我认为该工具也适用于 MPC 2500 的文件，我认为它们共享相同的格式。也许来自 MPC 500 的也可以工作，但不确定。我当然非常感谢有关这些 MPC 模型文件的使用的任何测试和反馈。

设置说明

使用独立的可执行文件

如果您不想在操作系统上安装 Python，并且对运行最新的开发版本不感兴趣，只需使用自 v1.2 版本以来可用的独立可执行文件：https://github.com/JOJ0/ mpc1k-seq/releases/tag/v1.2

• 对于 Windows 10 下载seq.exe
• 对于 MacOS X 10.13 下载seq （不确定较新的 MacOS 版本是否可以工作，请报告任何问题）

为了能够从系统上的任何位置执行seq ，请将其复制到搜索到的位置：

视窗

使用 Windows 资源管理器将 seq.exe 文件复制到 c:windowssystem32

请注意，这是一个肮脏的黑客行为。如果您不想执行此操作或没有执行此操作的权限，则可以在命令提示符下“cd”到保存 seq.exe 的位置并从那里执行它:-)

苹果电脑操作系统

确保您位于保存 seq 的目录中。您的用户需要具有管理员权限。执行以下命令时，系统会要求您输入密码：

sudo cp seq /usr/local/bin/

Linux

请按照下一章中的步骤进行操作！

使用最新的开发版本

如果您使用上述可执行文件，请跳过本章

首先，使用python --version检查系统上是否已有 Python 版本

你需要Python 2.7.x

克隆 github 存储库并跳转到该目录。

 git clone https://github.com/JOJ0/mpc1k-seq.git
cd mpc1k-seq

视窗

在这里下载 msi 安装程序

通过将克隆的存储库目录添加到系统％path％变量来安装该工具，

或者只是快速而肮脏地将其复制到系统搜索路径中已有的路径

copy seq.py c:windowssystem32

苹果

Mac OS X 10.11“El Capitan”预装了 Python 2.7.6，这是该实用程序开发和测试的版本。 OX X 10.8 有 Python 2.6，它可能也可以工作。 10.9 及更新版本都有 2.7.x，这应该没问题。

如果您没有上述内容，请从此处安装最新的 2.7 软件包或使用 homebrew 获取它。

安装工具

cp seq.py /usr/local/bin/

Linux

您很可能已经有一个正在运行的 Python 版本！按上述方法检查！

一些现代 Linux 发行版已经默认使用 Python 3.x，您必须安装 python2 包

基于 Debian 的系统

 apt install python2.7

基于红帽

 yum install python27

并将脚本的第一行设置为使用此 python 版本（例如#!/usr/bin/python2.7 ）

最后，安装该工具

cp seq.py /usr/local/bin/

如何使用

如果您使用的是开发版本，则必须执行 seq.py 而不是 seq。进一步注意，Windows seq.exe 可以在没有 .exe 结尾的情况下执行。 MacOS 可执行文件名为 seq，没有以 seq 结尾的文件

该实用程序作为 UNIX 风格的命令行实用程序提供，因此在使用典型的 --help 或 -h 选项运行时显示其所有功能：

 seq -h


usage: seq [-h] [--search SEARCHTERM] [--replace REPLACETERM]
              [--correct-wav] [--correct-wav-bpm] [--filter BPM_LIST]
              [--correct-bpm] [--hex] [--verbose]
              path

positional arguments:
  path                  path of *.SEQ files to be processed

optional arguments:
  -h, --help            show this help message and exit
  --search SEARCHTERM, -s SEARCHTERM
                        search for given string in file contents
  --replace REPLACETERM, -r REPLACETERM
                        replace SEARCHTERM with REPLACETERM
  --correct-wav, -w     sets basename of .SEQ file to the place where
                        SEARCHTERM is found. Use this if your seq and wav
                        files are named identically
  --correct-wav-bpm, -p
                        replace BPM in found SEARCHTERM with BPM found in
                        filename
  --filter BPM_LIST, --bpm BPM_LIST, -b BPM_LIST
                        historically was used as a space seperated BPM list
                        but actually it is a simple filter: only filenames
                        containing one of the strings in the list, will be
                        processed
  --correct-bpm, -c     set BPM to the same as in filename
  --correct-length, -l  set the sequences looplength (bars) to the same as in
                        filename. Assumes value in filename is marked with
                        trailing "b" (eg 8b)
  --hex, -x             show hex values next to decimal and strings
  --verbose, -v         also show border markers and not yet studied header
                        information

简单的使用示例

仅显示当前目录中所有 seq 文件的元信息

 seq .

显示文件名中包含 64 或 512 的所有 seq 文件的信息（通常是 BPM 值）

 seq -b "64 512" .

还以十六进制显示值

 seq -b "64 512" -x .

搜索字符串

 seq -b "64 512" -x -s "FunkBG" .

将第一次出现的 SEARCHTERM 替换为 REPLACETERM（再次运行脚本以替换 SEARCHTERM 的下一个实例）

FIXME - “replacecount”可以在未来版本中配置

 seq -b "64 512" -x -s "FunkBG" -r "Blues01" .

更详细的使用示例

显示当前目录 ( . ) 中文件名包含 80 的所有 .SEQ 文件（ -b "80"或--filter "80"并在文件中搜索术语"FunkBG"

通常，如果我们想要搜索并替换音轨中的 wav 文件名，那么这很有用，但我们也可能使用它来替换（二进制）seq 中某处的 MPC“程序文件”(.PGM) 的名称文件。

让我们看一下命令行及其输出：

 seq -b "80" -s FunkBG .

* PATH used: .
* searching for "FunkBG" (after End of header)
* bpm_list (filter_list): ['80']

输出的第一部分向我们展示了保存在文件头中的元信息，例如版本、小节数和序列的 BPM。

在“标头结束”标记之后，我们看到找到了搜索词“FunkBG”，它很可能是音频轨道中 wav 文件名称的开头。

假设我们想要替换配置到 seq 文件中的部分 wav 文件名。奇怪的是，wav 文件的名称保存在不同位置的两个 8 字节块中。该脚本试图帮助我们查明它是否只是找到了 wav 文件名的一部分或其他内容（例如 pgm 文件名或其他字符串）。

接下来是我们替换该字符串的可能性：

--replace (-r)是最简单的替换形式，它只是将 REPLACETERM 放在找到 SEARCHTERM 的位置。如果 REPLACETERM 比 SEARCHTERM 长，它将覆盖剩余部分。

--correct-wav (-w)是当我们的 wav 文件与我们的 wav 文件命名完全相同时使用的选项（当然文件结尾除外）。这是我最常用的选项。对于 github 存储库中的示例 seq 文件，wav 和 seq 文件名已经相同，因此此选项目前不是很有用。

--correct-wav-bpm (-p)仅当 SEARCHTERM 包含代表 BPM 值的数字时才有意义。我将在另一个例子中展示它。

每个选项都准确地说明了它们将替换的内容，因此如果我们对其中一个选项感到满意，我们只需重新运行脚本并将替换选项添加到命令行即可。

例如，如果我们选择-r作为要使用的选项，因为我们想简单地将“FunkBG”替换为“PunkBG”，则这将是命令及其结果输出：

 seq -b "80" -s FunkBG -r "PunkBG" .

* PATH used: .
* searching for "FunkBG" (after End of header)
* replace is enabled! REPLACETERM is "PunkBG"

?? use underscores or dashes as seperating characters!
**     it would replace "Punk" with "Punk".
** If this all looks like crap, don't do it! Existing files will be OVERWRITTEN!

另一个更复杂的例子

这是我实际编写此脚本的用例。让我们使用上面示例中的文件，其中我们将 Funk 替换为 Punk，但让我们复制并重命名它们。您可以按照自己的喜好进行复制/重命名，例如 iOS X Finder 内置了一个不错的批量重命名工具。我现在直接在命令行上执行此操作：

 cp FunkBG_080_8bar.SEQ PunkBG_080_8bar.SEQ
cp FunkBG_080_8bar.SEQ PunkBG_090_8bar.SEQ
cp FunkBG_080_8bar.SEQ PunkBG_100_8bar.SEQ

好的，现在我们要将所有 3 个“Punk 序列文件”中的 wav 文件名设置为与文件名相同。我们首先搜索 Punk 并看看我们有什么。该文件夹中可能还有其他 seq 文件，因此我们使用--filter (-b)选项特别选择了 3 个文件：

 seq --filter Punk -s "PunkBG" .

* PATH used: .
* searching for "PunkBG" (after End of header)
* bpm_list (filter_list):	['Punk']

如果我们仔细检查这 3 个文件的输出，我们会发现这些有用的可能性

• --correct-wav (-w)可以替换音频轨道 wav 文件的名称，使其等于 seq 文件名。也在文件 2 和 3（副本）中
