What Are The Key Features?
Virtual design of custom pedals down to transistors and clipping stages.
Captures the sound of physical pedals or recordings to create digital models.
Exporting custom pedals into the wider Positive Grid signal chain ecosystem.
How much does it cost?
- Free core app
- Distortion Pack IAP
- Delay Pack IAP
- Modulation Pack IAP
The app uses a modular IAP strategy where the platform is free, but specific effect categories are gated. This allows for a low entry barrier but relies on high-intent users purchasing specialized packs.
Who Built It?

The outtake for BIAS Pedal
Strengths to defend, gaps to attack
Core Strengths
- Unique component-level circuit modeling
- Proprietary Tone Match technology
- Strong ecosystem integration with BIAS FX
Critical Frictions
- Broken ToneCloud authentication
- Frequent app crashes during IAP/Integration
- Outdated iOS UI (last updated 2021)
Growth Levers
- Unified authentication with BIAS FX 2
- Optimization for M-series iPad hardware
- AI-assisted circuit design
Market Threats
- High-velocity competitors like Moises
- User migration due to 'abandonware' perception
- Host-environment dominance by AUM
What are the next best moves?
Fix ToneCloud Authentication API
This is the #1 complaint theme; users are unable to access purchased or community content despite having valid accounts.
Stabilize BIAS FX 2 Integration Bridge
Users report crashes specifically when trying to move pedals into BIAS FX 2, breaking the core ecosystem value proposition.
Refresh iOS UI for Modern iPads
Sentiment data shows users perceive the app as 'abandonware' because the UI is not optimized for current hardware screen ratios.
Feature Gaps vs Competitors
- AI-driven stem separation (available in Moises)
- Advanced AUv3 hosting and MIDI mapping (available in AUM)
- High-frequency feature shipping/modern cloud sync (available in Moises)
Key Takeaways
BIAS Pedal is a technically superior product currently failing due to operational neglect. If Positive Grid does not fix the ToneCloud login and stability issues immediately, the app will lose its remaining power users to more modern, high-velocity platforms like Moises or AUM-hosted plugins.
Where Is It Heading?
Declining
iOS version has not been updated since 2021, leading to 'abandonware' sentiment.
Critical login failures in ToneCloud are preventing community feature usage.
v1.1.2 Android update (Feb 2026) indicates the developer has not fully shuttered the product.
