Why players say this

Steam review verdict

Great for Genesis music with a simple interface and stable performance, but the unintuitive software, poor sound quality, and frequent crashes hold it back.

What players like

Excellent for Genesis music: Users report the tool works wonderfully for creating Genesis/YM2612 music and is very good at making Genesis music. It is also praised as a great chiptune creator and tracker.

Great for retro game music: The software is considered good for producing retro video game music and can create legitimate retro video game tracks. It is dedicated to video game sound chips.

Easy and simple interface: The program layout is simple, and the interface is easy to use, providing just enough features without confusion or overload. This makes it accessible for making music or experimenting.

Stable and solid performance: Users report the program is solid and stable, running with complete ease on Steam Deck. It also brings plenty of chiptune sound to the desktop.

Broad sound modification options: The tool offers a broad array of ways to modify sounds for the Genesis, including easy selection of sound chips and editing FM patches. This flexibility is highly valued by users.

Common complaints

Software is not intuitive: The software is difficult to get working even with tutorials, and the UI has bizarre choices and non-functional features.

Poor sound quality: All sounds are botched, and playback runs at 10% speed, suggesting the program does not use the CPU or sound card correctly.

Crashes and instability: Users report crashes (2 in 3 hours) and issues possibly due to hastily pushed updates or multiplayer features, indicating stability problems.

RAM address limitations: The SID file is placed at $1000, crippling a basic program to 2KB user RAM, and the RAM address cannot be changed, severely limiting functionality.

Lack of SNES support: Users are disappointed that the software does not support SNES, which limits its utility for retro music creation.

Gameplay and performance

Tool for retro music creation: The product is primarily a tool for creating retro video game music, specifically chip tunes and Genesis music. It is described as a chiptune tracker and a music editor for NES.

Supports multiple retro consoles: The tool supports Sega Genesis, GameBoy, NES, PC Engine, Neo Geo, and Sega Master System, making it versatile for various retro platforms. This broad compatibility is a key feature.

Can export music to ROMs: The product can export music to ROMs, enabling users to integrate their compositions into actual games. This is a powerful feature for game developers.

Uses .dmp files for FM patches: The product uses .dmp files for FM patch files, which is a specific technical detail relevant to sound design. This format is likely important for users creating custom patches.

Supports MIDI keyboard input: The tool allows inputting notes with a MIDI keyboard, which is a convenient feature for musicians. This enhances the input flexibility.

Frequent game crashes: Players report experiencing two crashes within three hours of gameplay, indicating a stability issue that disrupts the experience.

Broken audio quality: All in-game sounds are described as botched, suggesting a widespread audio defect that affects immersion and clarity.

Playback speed glitch: The play song feature runs at only 10% of normal speed, making it nearly unusable and frustrating for players.

Recommendations

Worth full price for chiptune: A reviewer states the product is definitely worth the full price for those who enjoy making chiptune music. This positive endorsement is niche but clear.

Older free version recommended: One reviewer suggests using an older free version instead of the current paid one, implying the paid version may not offer enough added value. This feedback is specific but from a single source.

Good purchase overall: One reviewer simply says it's definitely a good purchase, indicating general satisfaction. This is a positive but vague endorsement.

General recommendation given: A reviewer gives a straightforward recommendation without specific details. This is a positive but low-information signal.

Player profiles

Disillusioned Veteran: Cautious and troubleshooting; they continue using the software but recommend alternatives to others. Motivation: To create music with a reliable tool, but they are currently working around bugs and questioning the value of the latest version. Stance: no buy.

Enthusiastic Beginner: Experimental and exploratory; they are figuring out the software and are optimistic about its capabilities. Motivation: To explore chip tune music creation and enjoy the learning process. Stance: buy.

Other review notes

Furnace offers more for free: Compared to Furnace tracker, which is free and does more, the product may lack value. This suggests a competitive disadvantage in features and pricing.

Steam release matches non-Steam version: The software is available on Steam and is identical to the non-Steam version. This indicates a straightforward distribution without platform-specific differences.

Multiplayer features are a gimmick: Multiplayer features were added as a sales gimmick, implying they are not essential or well-integrated. This may disappoint users seeking meaningful functionality.

Workshop for sharing instruments needed: A workshop for uploading and downloading instruments and songs is suggested. This would enhance community sharing and content creation.

MIDI importer requested: The reviewer suggests a MIDI importer, which would allow users to bring in external MIDI files. This is a common feature for music software.
