1. Introduction

■About this manual

This document explains how to operate SCSP/DSP/Linker.

■Overview

A single "executable DSP microprogram" is created by linking "modules" prepared for each single function. There are two main types of modules: "EFFECT modules" and "I/O modules."
Module link order and input/output connections can be specified using graphics on the screen.

The following minimum hardware is required:

• A complete personal computer system for Macintosh or Windows machines (a separate SCSI I/F board is required for Windows machines)

• SCSP software development board

• SCSI cable to connect the above two points

■Installation

Copy it from the master disk to an appropriate location on your hard disk.

■QuickStart

This section provides an overview of SCSP/DSP/Linker operations from startup to termination.

●Step 1: Start the linker application

Double-click the Linker icon on the finder to launch the application.

●Step 2: Open a new algorithm

Select “New” from the File menu, enter a file name, and press the return key to open a new algorithm edit window. The extension ".YLI" is automatically added to the file name.

●Step 3: Check the SCSI ID

SCSP/DSP/Linker automatically sets the SCSI ID for communication with the development board at startup. Select “SCSI ID” from the Option menu and check that the SCSI ID setting of the development board's hardware switch matches the displayed ID.

caveat	At this time, you can also change the SCSI ID by setting the ID and clicking “OK”. However, please be especially careful because if you set the SCSI ID incorrectly, the contents of the storage device (hard disk, etc.) connected via SCSI may be destroyed.

●Step 4: Build the effect algorithm

Step 4-1: Place the DSP input/output module
Select “I/O Modules” from the Window menu to open the “I/O Module” window.
Double-click the “Input (input to DSP)” and “Output (output from DSP)” modules in the “I/O Module” window, or select them by clicking, and then click the “Select” button. . The module will be placed at the last clicked position in the algorithm edit window.

reference

Drag the "I/O Module" window to a position where it does not overlap with the algorithm edit window so that the "I/O Module" window is always visible. This is useful when arranging modules consecutively.

Step 4-2: Place the effect module

Select “Effect Modules” from the Window menu to open the “Effect Module” window.
Place the effect module in the same way as the DSP input/output module.

Step 4-3: Connect between modules

Connect the modules placed in the algorithm edit window.
Click the output port of the module from which you want to extract output sound data, then click the input port of the module to which you want to input the sound data, and the modules will be wired. This connection determines the flow of sound data between each module.

●Step 5: Link

By selecting “Link” from the Process menu, the created effect algorithm will be linked. If the link is successful, the Link Result Information dialog is displayed. This dialog displays information regarding the usage status of DSP-related hardware resources.

●Step 6: Download

By selecting “DownLoad” from the Process menu, the linked effect algorithm will be downloaded to the target (development board) hardware. At this stage, the DSP will work according to the effect algorithm created.

●Step 7: Edit effect parameters

The parameter edit window can be opened by double-clicking the blank space (where no text is displayed) in each module placed in the algorithm edit window, or by selecting it and then selecting “Parameters” from the Window menu. It will be opened.
If you operate the scroll bar in this window with the mouse or enter a value directly into the text box and confirm with the return key, the parameter changes will be reflected in the effect in real time.

If you perform an edit that changes the sound data route, real-time editing of parameters will no longer be effective from that point on (in this state, "DownLoad" in the Process menu will be grayed out). In this case, if you link and download again, you will be able to edit parameters in real time again.

●Step 8: Save as file

Up to this point, information about links and downloaded effect algorithms only exists in the host machine's memory, but is not saved as a file. Once you have completed your effect algorithm, select “Save” from the File menu to save it.

●Step 9: Exit the linker application

Select “Quit” from the File menu to exit the linker application.
